Moderate sample. 464 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 1991 Audi 90 is considerably less reliable than the UK average, with a first-time MOT pass rate of just 66.5% against the national benchmark of 80%—a meaningful gap that reflects age-related wear. Equally concerning is that over one in five of these cars (20.5%) have presented dangerous defects at some point, which puts them in a higher-risk category for buyers.

These vehicles are running at typical mileage for their age (median 132,654 miles), but they're failing on an average of 1.91 issues per test and accumulating 7.0 advisories, suggesting multiple systems are degrading simultaneously. Before purchasing, get a pre-buy inspection focused on brakes, suspension, and fuel system integrity—the advisory count hints at widespread component fatigue.

The 1991 Audi 90 has a below-average first-time pass rate (66.5% 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 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 464 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.

What tends to go wrong

Across 464 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Brake wear 46.6%
Parking brake: efficiency below requirements · Nearside rear parking brake recording little or no effort
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Lighting 25.2%
Offside Front Macpherson strut has slight movement at the upper attachment · Nearside Front Macpherson strut has slight movement at the upper attachment · Offside Rear fog lamp not working · …
Usually cheap to fix. Worth confirming all lights work before collecting.
Tyre wear 24.5%
Nearside Front Tyre worn close to the legal limit · Offside Front Tyre worn close to the legal limit · Nearside Front Tyre tread depth below requirements of 1.6mm · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Other issues 17.6%
Fuel pipe/s corroded · Oil leak
Suspension & steering 16.9%
Nearside Rear wheel bearing has slight play · Offside Rear wheel bearing has slight play
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Exhaust & emissions 13.4%
