This 1998 Audi TT passes its MOT first time only 72.9% of the time, sitting noticeably below the UK average of 80%—a sign that age and condition are catching up with these now quarter-century-old sports cars. With 15.9% of vehicles having recorded a dangerous defect at some point, you're looking at a real reliability gamble here.

At 106,000 miles on average, these TTs are well-used, and the data backs that up: owners average 2.15 failures and 7 advisories per test, suggesting worn components and deferred maintenance are common. Before buying, get a pre-purchase inspection focused on the cooling system, electrics, and suspension—the high advisory count points to these being typical problem areas on aging TTs.

We have limited data for the 1998 Audi Tt — treat the figures below as indicative rather than definitive.
