Reliability Trend

Newer Audi TTs pass their MOT more often than older ones, by 15 percentage points on average, which is mostly down to age and wear.

Mileage Across Years

The oldest model in our data (1999) averages 122,142 miles, while the newest (2022) averages 17,628 miles. Older models have covered serious mileage, so suspension and drivetrain wear are worth checking.
