This 2006 Smart Forfour Coolstyle 75 is noticeably less reliable than the UK average, with a first-time MOT pass rate of 72.8% versus the national 80%—a meaningful gap that suggests you're buying into higher-than-typical repair risk. More concerning, 40.2% of these vehicles have suffered a dangerous defect at some point, which is a serious red flag for structural or safety system issues.

These cars average around 68,800 miles on the clock for their age, which is typical, but they're racking up 4.66 failures and 19.1 advisories per test—the high advisory count suggests chronic wear across multiple systems rather than isolated problems. Before committing to one, insist on a full independent inspection focusing on suspension, steering, and braking components, and factor in regular maintenance costs to your budget.
