Should I check the MOT history before buying a 2008 Mercedes Benz Cls?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2008 Mercedes-Benz CLS passes its MOT at 79%, virtually level with the UK average of 80%, but over half of these cars have recorded a dangerous defect at some point—a significant concern for a buyer. Diesel models (78.8% pass rate) struggle slightly more than their petrol counterparts (81.9%), suggesting fuel type matters here.

These cars are averaging 85,000 miles at test time, which is reasonable for a 16-year-old model, but they're racking up an average of 3.49 failures and a hefty 20.7 advisories per MOT cycle—pointing to the CLS's complexity and high maintenance burden. If you're considering one, budget for regular and specialist work; the dangerously high defect rate means a thorough pre-purchase inspection by a Mercedes specialist is non-negotiable.

The 2008 Mercedes Benz Cls has a decent first-time pass rate (79%), 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 20.7 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 2,421 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.
