The 1991 SEAT TERRA is a below-average MOT performer, with a first-time pass rate of 67.8% against the UK average of 80%—meaning roughly one in three fail their test. The good news is that dangerous defects are uncommon at 6.6%, so serious safety issues aren't a widespread pattern across these cars.

These Terras are now over 30 years old and showing it, with an average mileage of 57,802 miles suggesting they're mostly low-milers kept more for hobby use than daily driving. The typical car racks up 2.4 advisories per test, indicating aging wear rather than catastrophic failure, but you should expect to budget for incremental repairs. If you're considering one, get a pre-purchase inspection from a mechanic familiar with 1990s Seats to assess corrosion, rubber seals, and fuel system condition—the issues likely causing those 0.6 average failures per vehicle.
