This 2003 Mercedes C180 is a serious reliability red flag: only 6.4% pass first time against the UK average of 80%, and the petrol version has a 0% pass rate across 120 vehicles tested. While dangerous defects are absent, this isn't reassurance—it reflects a cohort so unreliable that most don't survive to MOT in safe condition.

At 102,000 miles average, these cars are worn but not excessively so for their age; the real issue is that they're failing on routine items, not just accumulated mileage wear. If you're considering one, budget heavily for immediate repairs before purchase and factor in ongoing maintenance costs—this isn't a car to buy on price alone.
