The 2015 Smart Forfour passes its MOT slightly above the UK average at 81.4%, which is reassuring, but 40.4% of vehicles have recorded a dangerous defect at some point—well above the typical threshold and a genuine concern for prospective buyers. This suggests recurring structural or safety issues rather than isolated cases.

At 36,709 miles median, these Fortefours are relatively lightly used for their age, yet they're accumulating 9.5 advisories per vehicle on average, indicating wear and minor faults are common even at low mileage. Budget for regular maintenance and have any used example inspected thoroughly before purchase, paying particular attention to suspension and brake components where dangerous defects tend to cluster on this model.

The 2015 Smart (mcc) Forfour has a decent first-time pass rate (81.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 9.5 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 5,745 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.
