The 2004 Smart Forfour's 72.8% first-time pass rate trails the UK average of 80% by a meaningful margin, and more concerning, 35.6% of these cars have recorded dangerous defects during their MOT history—well above the threshold for buyer concern. Petrol and diesel versions perform similarly (73.0% and 71.7% pass rates respectively), so fuel choice won't materially improve your odds.

At nearly 70,000 miles median mileage, these 20-year-old cars show typical wear for their age, but the real red flag is the average 4.77 failures per vehicle—suggesting systemic durability issues rather than isolated problems. Plan for roughly 21 advisory items per test and budget accordingly; if you're considering one, a pre-purchase inspection by a technician familiar with Smart's known weaknesses (particularly electrical and suspension) is not optional.

The 2004 Smart (mcc) Forfour has a below-average first-time pass rate (72.8% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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.

🔍 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 1,094 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.
