Which Tvr models fail their MOT less for their age?
In 2024, 89.2% of MOTs on the 4 Tvr models published here passed (86.7% first time, 2.5% after a fix at the test centre), from 4,542 first tests. Allowing for age (not mileage), these Tvr models fail 63% less often than normal: brand MOT Risk Index 36.6 (95% CI 34.0–39.4; 100 = normal).
No single Tvr model has 10,000 first tests, so none is named best or worst here; every model's figure is in the chart and the table (the brand index uses all 4,542 tests).
