The '''Chevrolet Monza''' is a [[Subcompact car|subcompact]] automobile which was produced by [[Chevrolet]] from 1974 until 1980 for the 1975 through 1980 [[model year]]s. The Monza is based on the [[Chevrolet Vega]], sharing its [[wheelbase]], width, and standard [[inline-four]] engine. The car was designed to accommodate the GM-[[Wankel engine|Wankel]] rotary engine, but due to mediocre fuel economy and emissions-compliance issues the engine was cancelled, and a V8 engine option was substituted.<ref name= MTrend53>{{cite journal| journal= [[Motor Trend]]| date= March 1975| title= [Unknown]| volume= 29| number= 3| page= 53}}</ref> The Monza name has also been used for [[Monza (disambiguation)|several other cars]].

Introduced for the 1975 model year, the Monza 2+2 and Monza Towne Coupe competed with the [[Ford Mustang II]] and other sporty coupes.<ref name="h-body.org">h-body.org</ref> General Motors' [[GM H platform (RWD)|H-body]] variants, the [[Buick Skyhawk]] and [[Oldsmobile Starfire]], were produced using the Monza 2+2's body with grille and trim variations and [[Buick]]'s 3.8 liter [[V6 engine]]. The [[Pontiac Sunbird]] variant was introduced for the 1976 model year, initially offered only in the Monza Towne Coupe body with the 2+2 hatchback added for the 1977 model year. The Monza nameplate originated in mid-1960 for the sport version of the [[Chevrolet Corvair]].

==History==
===Origin===

The Monza 2+2 debuted as a single-model 2+2 hatchback. The Monza is {{convert|4|in|mm}} longer and weighs {{cvt|180|lb}} more than the Vega from which it is derived.<ref name="1975 Chevrolet Monza brochure">{{cite book| title= 1975 Chevrolet Monza| type= brochure| publisher= Chevrolet | year= 1974}}</ref> General Motors' [[John DeLorean]] nicknamed it the "Italian Vega", citing styling with a strong resemblance to the [[Ferrari 365 GTC/4]].<ref>{{cite book |last= Wright| first= J. Patrick| title= On a Clear Day you Can See General Motors: John Z. DeLorean's Look Inside the Automotive Giant| location= New York| publisher= Smithmark Publishing| year= 1979 |isbn= 0-9603562-0-7}}</ref>

GM had planned to introduce the GM [[Wankel engine|Wankel]] rotary engine (licensed from [[NSU Motorenwerke AG]]) in the Monza's 1975 model. Rotary issues included mediocre fuel economy compounded at a time of comparatively high fuel prices following the [[Arab Oil Embargo]] of 1973, and GM canceled the engine (this was the same rotary engine that AMC had planned to source from GM for the 1975 Pacer). Thus, the 1975 Chevrolet Monza was launched carrying a conventional piston engine instead.

===Overview===
The 1975 Monza 2+2 houses then-newly approved rectangular headlights and a slot-style grille in a slanted nose made of resilient [[polyurethane]]. The side window louvers are functional, part of the flow-through ventilation system. The Monza 2+2's two-door [[hatchback]] body style is shared with the Pontiac Sunbird, [[Oldsmobile Starfire]] and [[Buick Skyhawk]].<ref>{{cite journal| journal= [[Motor Trend]]| date= September 1974| title= [Unknown]}}</ref> The standard engine was the Vega's aluminum-block [[GM 2300 engine|{{convert|140|cuin|L|1|abbr=on}}]] [[inline-four]] engine with a single barrel [[carburetor]] generating {{convert|78|hp}} at 4,200 [[Revolutions per minute|rpm]]. Optional was the two-barrel carburetor version that generated {{convert|87|hp}} at 4,400 rpm.<ref name="1975 Chevrolet Monza brochure"/> Chevrolet's new {{convert|262|cuin|L|1|abbr=on}} V8 engine was optional. The smallest V8 ever offered by Chevrolet, it featured a Rochester two-barrel carburetor and generated {{convert|110|hp}} at 3,600 rpm.  For 1975 only, Monzas sold in California and high altitude areas met the stricter emissions requirement by substituting a version of the {{convert|350|cuin|L|1|abbr=on}} [[V8 engine]] with a two-barrel carburetor tuned to just {{cvt|125|hp|kW|0}}. The Monza 2+2 and its Buick and Oldsmobile variants feature GM's first use of a torque arm rear suspension, also adopted for the 1975 [[Chevrolet Cosworth Vega|Cosworth Vega]] introduced mid-1975, and later, all 1976–1977 Vegas and [[Pontiac Astre]]s.<ref>{{cite book| title= 1975 Chevrolet Monza|type= brochure| publisher= Chevrolet}}</ref><ref>{{cite book| title= 1975 Chevrolet Cosworth Vega| type= brochure| publisher= Chevrolet}}</ref><ref>1976 & 1977 Chevrolet Vega & Pontiac Astre brochures</ref> The basic design was also incorporated into GM's third and fourth generation F-bodies, the [[Chevrolet Camaro]] and [[Pontiac Firebird]].

In April 1975, the Monza Towne Coupe was introduced — a [[notchback]] body-style with a conventional trunk featuring different sheetmetal than the 2+2 hatchback, but sharing its windshield and front fenders.<ref>{{cite book| title= 1975 Chevrolet Monza| type= brochure| date= March 1975| publisher= Chevrolet}}</ref>  It features single round [[headlamps]], instead of the dual rectangular headlamps on the 2+2.  The Towne Coupe was offered in response to the sales success of the [[Ford Mustang II]] notchback coupe and its luxury version, the Mustang II Ghia. The Towne Coupe is {{convert|1.5|in|mm}} shorter and {{convert|135|lb|kg}} lighter than the 2+2 and has slightly more rear head room.

A lower priced "S" version of the 2+2 hatchback was introduced mid-year. It featured as standard the Vega one-barrel engine with a three-speed [[manual transmission]]. The sport suspension, full console, sport steering wheel, day/night rear-view mirror and wheel opening moldings were deleted on the "S". The Chevrolet Monza 2+2 won ''[[Motor Trend]]'' magazine's [[Motor Trend Car of the Year|Car of the Year]] award for 1975.<ref>{{cite journal| journal= Motor Trend| date= February 1975| title= Car of the Year}}</ref>

===Model year changes===
The 1976 {{cvt|140|cuin|L|1|abbr=on}} four-cylinder engine, as used in the Vega, got some refinements. Named "Dura-built 140", it features quieter hydraulic lifters eliminating valve adjustments. The basic four developed 70 horsepower, but two-barrel carburetion increased the rating to 84. The 1976 model was the introduction of Chevrolet's new 5.0 liter (305 CID) V8 engine with a two-barrel carburetor generating {{convert|140|hp}} at 3,800 rpm, but only for California and high-altitude Monza customers, and replaced the 350 V8. The 262 was again the optional engine in 49 states. A redesigned dashboard replaced the Vega-derived one. A mid-year option for 1976 was a "<u>Sport</u>" front end available for the Towne Coupe, which featured the 2+2's polyurethane front end and quad headlamps. The Monza Spyder equipment package was introduced in 1976 for both the 2+2 hatchback and Towne Coupe. It featured a two-barrel carburetor version of the four-cylinder engine as standard, a floor console, sport steering wheel, F41 suspension with larger front and rear stabilizer bars, and special shock absorbers. This equipment had been standard on the original 1975 2+2 (excluding the mid-year "S" model).<ref>{{Cite web|url=http://oldcarbrochures.org/North-America/Chev/1976-Chevrolet/1976-Chevrolet-Monza-Brochure|title=1976 Chevrolet Monza brochure|website=Old Car Brochures|archive-url=https://web.archive.org/web/20190210100104/http://oldcarbrochures.org/North-America/Chev/1976-Chevrolet/1976-Chevrolet-Monza-Brochure|archive-date=10 February 2019|access-date=9 February 2019|url-status=dead}}</ref>

The 1977 Monza was highlighted by two new Spyder option packages available only for the 2+2 hatchback, one being a $274 Z01 performance equipment package and the other an additional $199 Z02 appearance package.<ref>{{Cite web|url=http://oldcarbrochures.org/North-America/Chev/1977-Chevrolet/1977-Chevrolet-Monza-Brochure|title=1977 Chevrolet Monza brochure|website=Old Car Brochures|archive-url=https://web.archive.org/web/20190210100112/http://oldcarbrochures.org/North-America/Chev/1977-Chevrolet/1977-Chevrolet-Monza-Brochure|archive-date=10 February 2019|access-date=9 February 2019|url-status=dead}}</ref> An {{convert|84|hp}} four-cylinder engine was standard, but Monzas could be ordered with a {{convert|145|hp}} {{cvt|305|cuin|L|sigfig=2}} V8 instead. The Monza dashboard contained round gauges in a brushed-aluminum instrument panel. The Towne Coupe Cabriolet was deleted, but a half-vinyl roof and opera windows could still be ordered.

The Monza “Mirage” was a one-year only (1977) sporty body modification package produced by Michigan Auto Techniques (MAT), an [[Aftermarket (automotive)|aftermarket]] company contracted by GM; the Mirage was painted white, with red and blue racing stripes along the length of the car. It also featured flared body panels and a special airdam and spoiler. The vehicles were built in GM's St. Therese plant, and sent to MAT for modification, after which MAT would ship completed cars to the dealer. There were approximately 4,097 1977 Mirages made by MAT,<ref name="h-body.org">h-body.org</ref> but there were also Mirages created by Chevrolet dealerships, as the body add-ons and stripes were available through the dealer parts department. The 5.0 liter (305 CID) engine was the only V8 option for the 1977 model year. The standard Vega 2.3 aluminum-block engine was discontinued at the end of the model year, replaced with the Pontiac 2.5 "Iron Duke".

The 1978 Monza line expanded to include [[Rebranding (automobile)|rebadged]] holdovers from the Vega line, which ended production after the 1977 model year. Chevy grafted a new Monza front end onto the previous Vega hatchback and wagon body-styles. The [[Chevrolet Vega#1978–1979|Monza "S"]], marketed as the Monza price leader, used the Vega hatchback body. With production of only 2,000 units, it was speculated that this was simply an effort to use up a stock of leftover 1977 Vega hatchback bodies. The Monza wagon was also offered in an estate wood-trimmed version, using the Vega wagon body. The 1978 Monza line gained a new base coupe and 2+2 hatchback with round headlights in an upright front end with a crossbar grille and new tri-colored taillamps. The base 2+2 hatchback also used a new blunt rear taillamp panel incorporating the license plate mount and a conventional rear bumper; its enlarged taillights with square amber turn signals were also used on notchback coupes. The new <u>Monza Sport series</u> was offered in both 2+2 hatchback and notchback body styles, using a modified version of the previous quad rectangular headlamps, now above a full-width open-slot grille. The 2.5 liter (151 CID) inline-four "Iron Duke" was standard for 1978, replacing the Vega's inline-four engine. Engine options were a Buick-designed 3.2 liter (196 CID) V6 engine with a two-barrel carburetor that produced {{convert|90|hp}} at 3,600 rpm.  Replacing the 3.2 liter V6 in California and high-altitude areas was Buick's 3.8 liter (231 CID) {{cvt|105|hp}} V6 engine. Four-cylinder engines and the 3.2 liter V6 were not available in high-altitude areas. The {{cvt|145|hp}} 305 cubic-inch V8 remained optional in all but the "S" hatchback and wagon models. Discontinued at the end of the 1978 model year were the S hatchback, Towne Coupe sport option and the estate version of the wagon.<ref>{{cite book| title= 1978 Chevrolet Monza| type= brochure| publisher= Chevrolet | date= January 1978}}</ref>

The 1979 Chevrolet Monza lineup was trimmed to four models.  Added standard equipment for 1979 included an AM radio, tinted glass, bodyside moldings, and sport steering wheel. Only the 2+2 sport hatchback kept the sloped Euro-look front end; others had a freshened grille. A more-potent standard {{convert|151|cuin|L|1|abbr=on}} four-cylinder with a redesigned cross-flow cylinder head and two-barrel carburetor developed 90-horsepower — five more than in 1978. Three optional engines were available: the {{cvt|105|hp}} {{convert|196|cuin|L}} V6, {{cvt|115|hp}} 231 V6, and {{cvt|130|hp}} 305 V8. The Spyder performance package cost $164 and the Spyder appearance package added $231. All Monzas had a color-keyed instrument panel, and all except the base coupe had a center console, and corrosion protection was improved. Discontinued at the end of the 1979 model year were the Monza wagon, the {{cvt|196|cuin|L|sigfig=2}} V6 and the {{cvt|305|cuin|L|sigfig=2}} V8.<ref>{{cite book| title= 1979 Chevrolet Monza| type= brochure| publisher= Chevrolet }}</ref>

The 1980 model year lineup consisted of a base 2+2 hatchback, notchback, and 2+2 sport hatchback; the 151-cubic-inch (2.5-liter) four-cylinder engine remained standard and the only engine option was the 3.8 liter (231 CID) Buick V6. The wagon was discontinued as the Citation hatchbacks offered equal cubic cargo capacity with the rear seats down along with better rear-passenger accommodation. Chevrolet decided to discontinue the Monza at the end of the 1980 model year although production of 1980 models continued to the end of calendar 1980 with its "1982" Cavalier replacement debuting in early calendar 1981.<ref>{{cite book| title= 1980 Chevrolet Monza| type= brochure| publisher= Chevrolet }}</ref>

===Monza Spyder===
The "Spyder" nameplate had been used to designate the 1962–1964 Corvair turbocharged model. The "Spyder" name was introduced for the Chevrolet Monza in 1976. This package included performance equipment and some small appearance items.  The Monza Spyder equipment package was available on all 2+2 hatchbacks and Monza Towne Coupes (with the "sport equipment" package) with five-speed manual and Turbo Hydra-matic [[automatic transmission]]s.  The Spyder equipment package included a two-barrel, Dura-Built 2.3 litre engine, floor console unit, large front and rear stabilizer bars, special shock absorbers, steel-belted radial ply blackwall tires, wheel opening mouldings (chrome), day-night inside mirror, a sport steering wheel (two-spoke), a special instrumentation and "stitched" instrument panel pad with added wood-grain vinyl accents (standard on 2+2), distinctive "Spyder" identification (script fender emblems, steering wheel horn button insert) and Spyder front facia and rear-lock cover.

Chevrolet made extensive changes to the Spyder package including separate equipment and appearance packages with separate RPO codes found on the build sheet.  The Spyder equipment package was a regular production option (RPO) Z01, while the Spyder appearance package was RPO Z02.  The Spyder packages were available on Monza 2+2 sport hatchbacks.  Spyder decal colors were determined by the body color of the Monza ordered.  There were four color combinations for 1977.  For 1979, there were six combinations, which included a green and a blue color scheme.

;Z01 – Spyder equipment : BR70-13C Steel-belted radial ply blackwall tires, sport suspension, sport steering wheel (two-spoke), center console, inside day-night rearview mirror, Spyder identification, wheel opening moldings (available if the Z02 – Spyder appearance package was not ordered), dual tailpipe system and white lettered tires were available in 1979.

;Z02 – Spyder appearance : Black highlights on front, side and rear of body headlight openings, parking light openings, windshield, rear window and side window moldings, body sill, door and center pillar louvers, rear end panel – (bright window moldings with black exterior), black or gold rear accents (taillight blackouts and rear end panel decals), body color front air dam and rear spoiler, Spyder emblems (front facia, rear lock cover and sport steering wheel horn button insert), body side stripes with Spyder lettering in red, white or gold depending on body color, black painted styled-steel wheels with trim rings and center caps, black sport mirrors, special hood decal and rear spoiler decal. For the 1980 model year, Chevrolet combined the Spyder equipment and appearance packages into one Spyder equipment package with an RPO code of Z29 and included newly re-designed bold Spyder side decals and a new front air dam that blends into the front fender wheel openings.  Spyder decal color choices (five) were based primarily upon the interior color specified rather than the body color as in previous years.

;Z29 – Spyder equipment package : BR70-13C steel-belted radial ply blackwall tires (with option for raised white lettering), sport suspension, black front and rear bumper rub strips, black headlights frames, black windshield, belt, side and rear window moldings (not available with black exterior), black painted body sill (also not available with black exterior), black door and center pillar louvers, black painted taillight frames, body color front air dam and rear spoiler, Spyder emblems on front facia, rear lock cover and sport steering wheel (horn button insert), black sport mirrors (LH remote, RH manual), rear spoiler and body stripes with Spyder lettering outlined in accent body colour, Spyder hood decal, black painted Rally II wheels with bright trim rings and center caps.<ref>{{cite book| title= Chevrolet Monza| type= brochure| publisher= Chevrolet | year= 1976–1980}}</ref>

===Wankel engine===
[[File:'74 GM Rotary engine.jpg|thumb|200px|1974 Vega RC2-206 Wankel]]
In November 1970, GM paid $50 million for initial licenses to produce the [[Wankel engine|Wankel rotary engine]], and GM president Ed Cole projected its release in three years. The GM Wankel was initially targeted for an October 1973 introduction as a 1974 Vega option. The [[General Motors Rotary Combustion Engine]] (GMRCE) had two rotors displacing {{convert|206|cid|L|abbr=on}}, twin distributors and coils, and aluminum housing,<ref name="Motor Trend, July 1973, p.52">{{cite journal| journal= Motor Trend| date= July 1973| title= [Unknown]| page= 52}}</ref>

Unwilling to face the [[gas mileage]] criticism that [[Mazda]] withstood, GM felt it could meet 1975 [[emissions standards]] with the engine tuned to provide better mileage. Other refinements improved mileage to a remarkable 20 mpg, but with the fuel breakthrough came related side-effect problems — apex seal failures, as well as a rotor tip-seal problem.<ref name="Motor Trend, July 1973, p.52"/> By December 1973, it was clear the Wankel, now planned for the Monza 2+2, would not be ready for either production or emissions certification in time for the start of the 1975 model year.<ref name= MTrend53 /> and after paying another $10 million against its rotary licence fees, the company announced the first postponement. ''Motor Trend'' in April 1974 predicted the outcome<ref name= MTrend74>{{cite journal| journal= Motor Trend| date= April 1974| title= [Unknown]}}</ref> — On September 24, 1974, Cole postponed the Wankel engine ostensibly due to emissions difficulties and retired the same month. General Motors admitted fuel economy for the rotary was sub-standard and postponed production in favor of further development. [[Pete Estes]] succeeded Cole as GM's president and never showed any special interest in the Wankel or in the perpetuation of Cole's ideas. Estes had previously decided to let the [[Chevrolet Corvair|Corvair]], another Cole project, expire, well before the celebrated attacks of [[Ralph Nader]].<ref name= MTrend74 />

=== End of the H-body ===
[[File:Chevrolet Monza.JPG|thumb|left|Chevrolet Monza]]
A total of 731,504 Monzas were produced in six model years.<ref name="h-body.org"/> General Motors replaced the [[rear-wheel drive]] (RWD) H-body Monza, Sunbird, Skyhawk, and Starfire in the spring of 1981 with a new, [[front-wheel drive]] (FWD), line-up, the [[GM J platform|J-car]] models: [[Chevrolet Cavalier]], [[Oldsmobile Firenza]], [[Buick Skyhawk]], [[Pontiac J2000]] and [[Cadillac Cimarron]], introduced as 1982 models. Because the forthcoming J-body cars were to be sold as 1982 models, there was a long production run of 1980 H-body models in order to provide sufficient inventory to carry dealers until the spring of 1981.

===United States===
[[File:DeKonMonza.jpg|thumb|Wynn's DeKon Monza]]
Chevrolet Monzas participated in the [[IMSA GT Series]] powered by [[Chevrolet Corvette]] engines. Chevrolet Monzas were the challengers in the new AAGT class. The class was designed to allow such cars to compete with the best GT cars in the world. The 1975 season was launched with the new cars that would compete with the dominating Porsche Carreras. A very liberal set of rules allowed some body panels to be retained – the windshield, the rear window and the roof. Everything else was built from scratch.

The IMSA racer and future triple [[24 Hours of Le Mans|Le Mans]] and dual [[Daytona 24 Hours]] winner [[Al Holbert]] saw the Monza's potential. By the end of the 1975 season, he had ordered a brand new car, built and prepared by Lee Dykstra and American-based Australian [[Trans-Am series|Trans-Am]] driver [[Horst Kwech]] at DeKon Engineering. Chassis No. 1008 was used starting the 1976 season. In 1976 and 1977, he was the IMSA Camel GT champion, beating [[Hans Stuck]], [[Brian Redman]] and [[Peter Gregg (racing driver)|Peter Gregg]]. In Holbert's successful 1977 campaign he captured another Camel GT crown. However, it would be the last title for an American car. The Porsche 935s were becoming unbeatable right from the beginning of the 1978 season. However, the DeKon built Chevrolet Monza left its footprint on the IMSA Camel GT. They were quite unbeatable in 1976–1977. Chevrolet Monzas were seen in IMSA until 1986.<ref>{{cite web| work=Roadcarvin Magazine |url=http://www.roadcarvin.com/node/1041 |title=2007 Rolex Monterey Historic Races – 1977 DeKon Monza |via= Roadcarvin.com |access-date=2009-04-27}}</ref> Chris Cord's original DeKon Monza is owned and vintage raced today by Ken Epsman, while Holbert's Monza has been found and is now undergoing restoration in northern California.

===Australia===
The Monza also saw success in Australia in the late 1970s and through the 1980s in the [[Australian Sports Sedan Championship]] (ASSC) (renamed the [[Australian GT Championship]] in 1982). GM's presence in Australia was represented by [[Holden]] which was Australia's own manufacturer of GM vehicles. Neither the Nova or the Monza were ever offered to the Australian public. [[Allan Moffat]] otherwise imported a DeKon Monza to Australia and won the [[1976 Australian Sports Sedan Championship|inaugural]] ASCC in 1976 (also driving a 'Cologne' [[Ford Capri|Ford Capri RS3100]]). In 1978, driver and prominent businessman [[Bob Jane]] imported a DeKon Monza, which was rebuilt and engineered by his chief mechanic Pat Purcell and driver-engineer Ron Harrop. Jane had some success with the car but it was at times plagued by poor reliability, and when he retired at the end of 1981 due to a back injury, he recruited touring car star driver [[Peter Brock]] to drive the car. Brock drove the 6.0L Monza in the [[1982 Australian GT Championship|1982]] and [[1983 Australian GT Championship|1983]] GT championships for Jane. A second Monza was built by Jane's team which was to have been raced in an IMSA street race in [[Miami]] in the early 1980s by Brock and Australia's {{f1|1980}} [[Formula One]] champion [[Alan Jones (racing driver)|Alan Jones]], though it was never raced in the USA.

In the 1982 championship, Brock came up against Jones in a well sorted, and slightly more powerful [[Porsche 935]] turbo. Brock and the Monza consistently matched the speed of Jones and the two put on some of the best racing ever seen in Australia, but reliability was still a problem with the car and results were not forthcoming.<ref>[https://www.youtube.com/watch?v=I0w33CRP0DI 1982 Australian GT Championship – Adelaide]</ref> Brock was involved in a spectacular start line crash in round three of the 1983 championship at the [[Adelaide International Raceway]] and the Monza was not seen again until the end of the year when Brock finished third in a GT/[[Australian Sports Car Championship|sports car]] invitation race as a support to the [[1983 Australian Grand Prix]]. After being rebuilt again by Purcell, Jane sold the car to former race driver Alan Browne, who put his [[1982 Bathurst 1000]] pole winning co-driver [[Allan Grice]] in it for the [[1984 Australian GT Championship|1984 GT championship]]. Grice and the Monza easily won the championship, winning all but one round. Grice, who had never gotten along with Purcell, was so impressed with the car after he first drove it that he  phoned Purcell to compliment him on what he felt was the best race car he had driven in his more than 20-year career.

The Monza was then prepared for the [[1984 Sandown 1000]], the final round of the [[1984 World Endurance Championship]]. Driving alongside renowned Ron Harrop and fellow touring car ace [[Dick Johnson (racing driver)|Dick Johnson]], Grice qualified the {{Convert|650|bhp|kW PS|0|abbr=on}} Monza a credible 18th (second in the invitation AC Class for Australian GT and [[Group A Sports Car]]s), and claimed the car lost nothing on the straights to the race winning [[Porsche 956]]B's, but lost time in the turns to the [[Ground effect (cars)|ground effects]] Porsches. Johnson later claimed that the car had more grunt from its 6.0L V8 than its handling deserved. They were eventually disqualified for receiving outside assistance from track marshals after completing 114 of the races 206 laps.

After 1984, Browne sold the Monza to veteran racer Bryan Thompson, who used it (along with his usual [[Chevrolet small-block engine (first- and second-generation)|Chevrolet]] powered, twin turbo [[Mercedes-Benz SLC-Class|Mercedes-Benz 450 SLC]]) to win the [[1985 Australian GT Championship]]. Thomson competed in the car over the next few years before rebuilding it over the 1988–89 off-season which also saw the Monza body shell replaced with that of a [[Toyota Supra#A70|Toyota Supra]]. He then sold the car in 1990 to an unknown owner who then sold it to longtime Sydney-based sports car racer Des Wall.
