The 2007 Mercedes R-Class barely keeps pace with the UK average at 78.9% first-time pass rate, but a serious red flag is that 38.8% of these vehicles have recorded a dangerous defect during their MOT history—well above the typical threshold—making this a model to inspect very carefully before purchase. Diesel versions, which dominate the used market here (915 of 1,022 vehicles), pass slightly worse at 78.4% compared to the rare petrol models at 82.9%.

At around 89,000 miles median, these cars are showing their age with an average of 3.42 failures and 18 advisories per test, suggesting ageing components and systems that need ongoing attention. If you're seriously considering one, budget for maintenance surprises and have a pre-purchase inspection focus hard on brake systems, suspension, and electrical faults—the advisory count signals chronic wear rather than isolated issues.

The 2007 Mercedes Benz R Class has a decent first-time pass rate (78.9%), 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 18 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 1,022 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.
