These 1993 Mercedes-Benz 300s are slightly below the UK average for reliability, with a first-time pass rate of 74.3% compared to 80% nationally—and critically, 22.1% have recorded dangerous defects, making safety a genuine concern for used buyers. Diesel variants underperform petrol slightly (73.2% vs 75.6% pass rate), though the difference is modest.

At a median of 167,800 miles, these cars are well-used for their age, yet they're still generating an average of 2.89 failures per test, suggesting wear is catching up with them. With 15.1 advisories per vehicle on average, expect to budget for several minor fixes—but before purchasing any example, insist on a full service history and independent inspection, particularly around brake systems and suspension where many of the dangerous defects are likely to lurk.

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 15.1 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 1,207 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.
