The Audi B2 platform, sold as the 80 and 90 in Europe and the 4000 in North America, was a major step forward for the brand. Produced from 1978 to 1986 with sharp styling by Giorgetto Giugiaro, it introduced key Audi technologies. Most importantly, this was the first sedan platform to receive the revolutionary quattro all-wheel-drive system, which debuted in the US on the 1984 4000S Quattro.
Collectors prize the B2 for its direct link to Audi's rally heritage and its durable engineering. The 4000S Quattro is the most desirable model, offering the celebrated 2.2L inline-5 engine and all-wheel drive in a practical sedan package. Its mechanical simplicity and distinctive engine note make it a favorite among classic German car enthusiasts, but finding clean, unmodified examples is becoming a challenge.
The market for these cars is broad. Standard front-wheel-drive models can still be found for under $10,000, making them an accessible entry point to classic Audi ownership. The quattro models carry a significant premium, with average sale prices around $14,000. Exceptional, low-mileage examples, like a 1987 4000CS Quattro that sold for $84,337, represent the top of the market and show the strong demand for the very best cars.
Buying Tips
- Rust is the biggest enemy. Check under the battery tray, along the rocker panels, in the spare tire well, and around the front and rear windscreens.
- The inline-5 engine is known for its durability, but look for signs of oil leaks from the valve cover gasket and cam seals. A detailed service history is a huge plus.
- On Quattro models, test the manually locking center and rear differentials. The vacuum-actuated system can develop leaks, making the lockers inoperable.
- Interior parts are scarce. Pay close attention to the condition of the dashboard for cracks, the seat fabric for tears, and the headliner for sagging. A complete, tidy interior is a major bonus.
- Listen for whining from the transmission and differentials. The gearboxes are strong, but worn synchros on manual cars or noise from the drivetrain can signal expensive repairs.
Prices range from $2,750 for project cars to $84,337 for concours-quality Quattro models.
