• Last service: Recently serviced in March 2026 (receipt available) at a total cost of approximately CHF 4,300.
Engine: Total mileage approx. 157,000 km (only about 8,000 km driven since 2021). Recently serviced in March 2026. The engine sounds and runs superbly. A timing belt replacement is recommended due to the vehicle’s age.
Electronics: Recently serviced in March 2026, during which numerous electronic components were replaced. Functions flawlessly. An air conditioning service is recommended and is due.
Underbody & Wheels: The entire brake system was overhauled in 2021. The car is fitted with legendary BBS RS rims in excellent condition. All tires (Pirelli) were purchased in 2021 (approx. 8,000 km mileage). A replacement is recommended due to their age (5 years); additionally, one rear tire has grazed a curb—it is intact but should be replaced for your own safety.
Exhaust: The Ansa Marmitte muffler should be replaced or refurbished due to its age.
Body & Paint: The car was originally delivered from the factory in silver. It was repainted in garnet red during the Strosek conversion. It shows age-related signs of wear and patina; minor scratches and cosmetic imperfections are present. The edges of the rear Strosek wide-body kit show minimal stress cracks, which is very common in Strosek conversions. There are scratches under the front bumper.
Interior: Very well-preserved and in excellent condition for its age. The dashboard is crack-free. Beautifully preserved Recaro Classic leather front seats and a Momo leather steering wheel. The rear seats and door panels still feature the legendary, original “Pascha” factory upholstery. The JVC car stereo is a contemporary upgrade from the late 1980s.
Keys & Tools: All 3 original factory keys are present (keyed alike for all locks). The onboard tool kit and the air compressor in the trunk are complete. Includes the original spare tire (dated 1977) with factory tires, as well as the BBS key for removing the wheel covers.
Note: A custom-made front bumper is currently installed, which was ordered by the previous owner during the Strosek conversion in 1987.
