The 2008 Mercedes-Benz C barely keeps pace with the UK average at 79.7% first-time pass rate, but there's a real alarm bell here: 43.6% of these cars have recorded a dangerous defect at some point, well above the threshold that should concern a buyer. Petrol models pass slightly more often (81.2%) than diesels (78.7%), suggesting the diesel engines may be the weaker link as these cars age.

At 92,321 miles median, these 16-year-old cars are running close to typical for their age, yet they're still racking up an average of 3.39 failures per MOT and 19.5 advisories—a sign that the running costs and repair burden climb sharply once warranty ends. Before buying, get a pre-purchase inspection focused on the cooling system, electrics, and suspension, as these chronic issue areas are what's dragging down the pass rates.

The 2008 Mercedes Benz C has a decent first-time pass rate (79.7%), 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 19.5 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 23,760 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.
