This 2006 Smart Forfour has a first-time pass rate of 77.9%, just below the UK average of 80%, which suggests fairly typical reliability for its age—nothing alarming. However, 22.5% of these vehicles have recorded a dangerous defect at some point, which is higher than you'd want to see and worth taking seriously during a pre-purchase inspection.

The median mileage of 57,393 miles is reasonable for an 18-year-old car, but these vehicles are racking up an average of 3.41 failures and 15.4 advisories per MOT, indicating that wear items and minor issues accumulate quickly once problems start. Before buying, insist on a full service history and a thorough check of the suspension, brakes, and electrical systems, as these small cars tend to develop niggling faults rather than catastrophic ones.
