The 2003 SEAT AROSA passes its MOT first time at 74.1%, notably below the UK average of 80%, and a serious concern emerges in the safety data: 34.7% of these vehicles have recorded at least one dangerous defect during their MOT history, which is substantially higher than typical. Petrol and diesel versions perform similarly (74.2% vs 71.9% pass rates), so fuel type isn't a differentiator here.

At a median mileage of 52,864 miles for a 21-year-old car, these Arosas have been driven gently, yet they still average 4.85 failures and 21.3 advisories per test, indicating age and wear are catching up regardless. If you're considering one, get a thorough pre-purchase inspection focusing on brakes, suspension, and steering—the dangerous defect rate suggests these areas need particular scrutiny on older examples.

The 2003 Seat Arosa has a below-average first-time pass rate (74.1% 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 21.3 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 2,449 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.
