The 1999 Alfa Romeo 156 passes its MOT first time just 65.8% of the time—significantly below the UK average of 80%—and one in five of these cars have recorded a dangerous defect at some point, which is a genuine red flag for structural or safety issues. Petrol and diesel variants perform essentially identically, both around 66% pass rate, so fuel type won't help you dodge the reliability problems.

At nearly 93,000 miles on average, these cars are moderately worn for their age, yet they're still averaging 2.75 failures and 8.8 advisories per MOT—suggesting systemic maintenance issues rather than one-off wear. If you're considering a 156 from this era, budget for meaningful repairs, have a pre-purchase inspection focus on suspension, brakes, and structural integrity, and expect that you're buying into a car that will need more attention than most of its peers.

The 1999 Alfa Romeo 156 has a below-average first-time pass rate (65.8% 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 8.8 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 7,041 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.
