Should I check the MOT history before buying a 2006 Smart Forfour Brabus?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2006 Smart Forfour Brabus passes MOT first time in only 75.8% of cases, sitting 4.2 points below the UK average of 80%, which suggests mediocre reliability for its age. More concerning, 40.6% of these vehicles have recorded a dangerous defect at some point—well above what you'd expect—so structural and safety issues are a real risk with this model.

These cars are running at a reasonable 64,900 miles median for an 18-year-old vehicle, but the average of 4.06 failures per test and 23.4 advisories reveals persistent wear and accumulated problems. Before buying, get a full pre-purchase inspection focused on suspension, steering, and brake components, since the high dangerous defect rate suggests these areas are common failure points on the Brabus.
