The 1998 Alfa Romeo 156 passes its MOT first time in just 65% of cases, well below the UK average of 80%, which makes it a notably unreliable prospect by modern standards. Nearly one in five of these cars have recorded a dangerous defect at some point, a significant buyer concern that suggests potential safety issues lurking beneath the surface.

At just over 96,000 miles on average, these 26-year-old cars show typical mileage for their age, but they're averaging 2.6 failures and 8 advisories per test—well above what you'd expect for vehicles in this condition. Before committing to one, budget for immediate remedial work and have a pre-purchase inspection focus on brake systems, suspension, and electrical faults, which tend to be the repeat culprits on this generation.

The 1998 Alfa Romeo 156 has a below-average first-time pass rate (64.9% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 8 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 8 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 4,431 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.
