Should I check the MOT history before buying a 2010 Mercedes Benz Slk?

The 2010 Mercedes-Benz SLK passes its MOT slightly above the UK average at 82.6%, but that masks a serious concern: nearly 40% of these cars have recorded a dangerous defect at some point, making this a vehicle that demands close inspection before purchase. This high proportion of dangerous faults puts it firmly in problem territory for a buyer prioritizing safety and peace of mind.

At nearly 48,000 miles on average, these SLKs are showing typical mileage for their age, but they're racking up substantial maintenance costs—averaging 2.84 failures and 16.8 advisories per test. Before committing to one, budget for at least a pre-purchase inspection by a Mercedes specialist to identify any lurking electrical or suspension issues, and factor in that you're statistically likely to face multiple repairs in the coming years.

The 2010 Mercedes Benz Slk has a decent first-time pass rate (82.6%), 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 16.8 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 2,217 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.
