Should I check the MOT history before buying a 1998 Audi A8?

The 1998 Audi A8 is struggling: its 69.4% first-time pass rate sits 10.6 points below the UK average, and nearly one in three examples (31.8%) have recorded a dangerous defect at some point. This is a significant reliability concern that should give any potential buyer pause, particularly when considering the age and complexity of the model.

At 124,000 miles on average, these cars have been well-used, and the numbers explain why—they're racking up 3.6 failures and 13.7 advisories per test, suggesting ageing electrics, suspension wear, and cumulative mechanical fatigue typical of 26-year-old German luxury cars. Before purchasing, obtain a full service history and have a pre-purchase inspection focus on the fuel system, emissions equipment, and suspension components, which tend to be the culprits in A8 failures of this era.

The 1998 Audi A8 has a below-average first-time pass rate (69.4% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 13.7 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 730 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
