Should I check the MOT history before buying a 2014 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.

The 2014 Mercedes-Benz CLS passes its MOT slightly above the UK average at 83.8%, which is encouraging, but nearly 47% of these cars have recorded at least one dangerous defect during their test history—a genuinely high figure that demands careful pre-purchase inspection and full service records. Diesel and petrol variants perform similarly (83.7% and 86.2% respectively), so fuel type isn't a differentiator here.

At an average mileage of 63,950 miles for a 10-year-old car, these are relatively moderate-use examples, yet owners are seeing an average of 1.77 failures and 11.2 advisories per test, suggesting wear items and electrical niggles accumulate steadily. Before committing to one, have an independent pre-purchase inspection done and specifically ask the seller about any suspension, brake, or electrical history, as these typically drive the advisory count on this model.

The 2014 Mercedes Benz Cls has a decent first-time pass rate (83.8%), 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 11.2 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 2,031 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.
