Moderate sample. 334 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2005 Smart Forfour Passion is significantly less reliable than the UK average, with a first-time pass rate of just 72.5% versus the national 80%, and a concerning 32.6% of vehicles have recorded dangerous defects—well above acceptable thresholds for a buyer's peace of mind. The semi-automatic transmission variant doesn't appear to offer any advantage, as petrol models show the same 72.4% pass rate.

At 64,664 miles average, these cars are reasonably low-mileage for their age, yet they're averaging 4.06 failures and 17.3 advisories per test, suggesting inherent design or build weaknesses rather than wear-related issues. If you're considering one, budget for regular repairs and have a pre-purchase inspection focus on the gearbox, electrics, and cooling system—the high advisory count flags these as problem areas for the model.

The 2005 Smart Forfour Passion Semi Auto has a decent first-time pass rate (75.9%), 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 17.3 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 334 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.
