Moderate sample. 480 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 1980 Triumph Dolomite has a first-time MOT pass rate of 71%, which is notably 9 points below the UK average of 80%, signalling these cars tend to arrive at test with unresolved issues. Dangerous defects have been recorded on just over one in five examples (20.4%), which is a legitimate buyer concern worth investigating on any specific vehicle.
At an average mileage of around 56,000 miles for a 44-year-old car, these survivors are relatively low-mileage examples, yet they're still accumulating an average of 2.43 failures and 7.2 advisories per test—suggesting age-related decay in electrics, fuel systems, and trim rather than wear from use. If you're seriously interested in one, get a pre-purchase inspection focusing on rust, wiring harnesses, and fuel delivery, because the MOT data indicates these are common pain points.
The 1980 Triumph Dolomite has a below-average first-time pass rate (71% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
These stats describe 480 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.
