Should I check the MOT history before buying a 2006 Smart (mcc) Forfour?

The 2006 Smart Forfour is notably less reliable than the UK average, with a first-time pass rate of 74.4% against the national benchmark of 80%—and nearly 4 in 10 of these cars have suffered dangerous defects at some point, which is a serious buyer concern. Petrol and diesel variants perform similarly (74.6% and 73.6% respectively), so fuel type won't be a deciding factor here.

At 67,000 miles on average, these cars have covered reasonable mileage for their age, yet they're racking up 4.5 failures and over 20 advisories per test, suggesting widespread wear in multiple systems rather than one glaring weak point. Before committing to any 2006 Forfour, have a trusted mechanic inspect the brakes, suspension, and lighting in detail—the dangerous defect rate makes a pre-purchase inspection non-negotiable rather than optional.

The 2006 Smart (mcc) Forfour has a below-average first-time pass rate (74.5% 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.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 20.7 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 1,271 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.
