The 2003 Subaru Legacy passes its MOT first time in only 74.2% of cases, noticeably below the UK average of 80%, and nearly three in ten have recorded dangerous defects—a significant concern for buyers considering a vehicle now over 20 years old. This suggests the model has underlying durability issues or tends to suffer from deferred maintenance as it ages.

With a median mileage of 87,151 miles for a 21-year-old car, these Legacies have been driven moderately and aren't exceptionally worn by age alone, yet they still average 4.2 failures and over 23 advisories per test. Before committing, have a trusted mechanic inspect the suspension, brakes, and exhaust system—the advisories point to wear in these areas—and ask the seller for full service history to understand whether neglect or design weakness is behind the high failure rate.

The 2003 Subaru Legacy has a below-average first-time pass rate (74.3% 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 23.2 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 1,558 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.
