Should I check the MOT history before buying a 2001 Alfa Romeo 166?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

The 2001 Alfa Romeo 166 passes its MOT first time in only 66.2% of cases, significantly below the UK average of 80%, and over a third of these cars (35.5%) have recorded dangerous defects at some point—a serious red flag for any potential buyer. This is not a vehicle you should approach lightly, as the higher failure rate suggests systemic reliability issues rather than isolated problems.

At 81,000 miles median mileage for a 23-year-old car, these examples are relatively well-used, yet they're still averaging nearly 3.8 failures and 13.2 advisories per test, indicating wear and corrosion catching up quickly. Before buying, get a full pre-purchase inspection by an Alfa-familiar mechanic, focusing on rust, cooling system integrity, and electrical gremlins—these are the areas where the 166 typically disappoints.

The 2001 Alfa Romeo 166 has a below-average first-time pass rate (66.2% 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 13.2 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 563 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.
