The 1999 SEAT INCA is a notably unreliable proposition, with a first-time MOT pass rate of 65.5%—well below the UK average of 80%—and nearly 28% of vehicles in this cohort having recorded a dangerous defect at some point. This is a real concern for buyers; nearly three in ten examples have shown safety-critical failures, making pre-purchase inspection non-negotiable.

These Incas are running at typical mileage for their age (median 110,000 miles), but they're accumulating serious problems: the average vehicle racks up 3.2 failures and 12.2 advisories per test. If you're considering one, budget for immediate remedial work and factor in ongoing maintenance costs—this is a vehicle that demands hands-on ownership and a reliable mechanic on speed dial.

The 1999 Seat Inca has a below-average first-time pass rate (66.5% 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 12.2 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 972 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.
