The 2008 Mercedes-Benz CLK falls short of the UK average with a 76.8% first-time pass rate against the 80% benchmark, and more concerning, over half of these cars (53.2%) have recorded a dangerous defect at some point—a significant red flag for any prospective buyer. Diesel variants fare worse than petrol models, posting a 74.8% pass rate versus 78.1% for petrol, suggesting the diesel engine is the riskier choice here.

These CLKs show typical wear for their age with a median mileage of 62,584 miles, but they're troublesome when they reach the test bay, averaging 4.28 failures and nearly 25 advisories per vehicle. Before committing to one, have a pre-purchase inspection focus on the cooling system, suspension, and brake components, as these failure patterns suggest structural durability issues rather than minor aging.

The 2008 Mercedes Benz Clk has a decent first-time pass rate (76.8%), 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 24.8 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 3,513 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.
