About Smart Cars
Smart ranks joint 48th out of 70 car makes in our data (those with at least 1,000 MOT tests) by average MOT pass rate, at 80%. That's 5 points below the 85% average across all models in our data, so Smart owners should budget a bit more for maintenance.
With 61 models across 19 years of data (2003 to 2021), there's a narrow spread of just 8 percentage points between models, meaning Smart reliability is fairly consistent across the range.
