The C6 generation Audi A6, sold from 2005 to 2011, marked a turning point for the brand's design language. It was the first sedan to feature the prominent single-frame grille that now defines Audi's entire lineup. The C6 brought significant technology and powertrain advancements over its predecessor, offering everything from a 3.2L V6 to a 4.2L V8 and a supercharged 3.0L V6 later in the run.
Collectors are primarily focused on two specific variants: the S6 and the Avant. The S6 sedan is notable for its 5.2L V10 engine, a derivative of the motor found in the Lamborghini Gallardo. It offers a unique combination of understated looks and exotic-car performance. Avant wagons, regardless of engine, are also desirable for their practicality and rarity, with the 3.0T and 4.2 V8 models being particularly sought after.
Today's market for the C6 A6 is extremely broad. High-mileage early sedans are firmly in used-car territory, often trading for just a few thousand dollars. At the top end, excellent, low-mileage S6 models have sold for nearly $50,000, demonstrating a growing appreciation for the V10-powered sleeper. The average transaction price of around $16,550 shows a market balanced between basic transportation and special-interest models.
Buying Tips
- The 3.2L FSI V6 suffers from carbon buildup, while the 4.2L V8 has failure-prone timing chain guides that require an engine-out service.
- Check all functions of the MMI infotainment system. Screen or control module failures are common and expensive to fix.
- Test the optional air suspension through all its settings. Leaking air struts and failing compressors are common on higher-mileage cars.
- The 5.2L V10 in the S6 is a complex engine that requires specialist knowledge. Budget for expensive maintenance items like carbon cleaning and intake manifold repairs.
- On Avant wagons, check for water leaks from the panoramic sunroof drains and look for broken wires in the tailgate harness.
Prices range from under $2,000 for project cars to nearly $50,000 for low-mileage S6 examples.
