Buying a Used 2010 AUDI RS6
At 16 years old, the AUDI RS6 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins.

Note: with only 38 tests in our data, these figures should be treated as indicative rather than definitive.
Common Issues to Watch For
Based on the 2010 AUDI RS6's fuel type, age, and engine size, these are the most likely problem areas to check.
Timing Chain / Belt
Watch outAt 16 years old, check whether the timing belt has been replaced (typically due every 5-7 years or 60,000-100,000 miles). A snapped belt can destroy the engine.
Oil Consumption
Medium riskLarger petrol engines can develop higher oil consumption as they age. Check the oil level and look for blue smoke from the exhaust.
Rust and Corrosion
Watch outAt 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.
Suspension Bushings
Watch outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Clutch Wear
Medium riskWith an average of 84k miles, clutch replacement may be due (typical lifespan 60,000-100,000 miles). Budget £400-£800 for a new clutch kit.
Brake Discs and Pads
Medium riskHigh-mileage cars often need brake disc replacement, not just pads. A full set of discs and pads costs £200-£500 per axle.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
