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

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.

What corrosion should I look for when inspecting a 2010 Mercedes Benz Sl?

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.

Moderate sample. 414 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2010 Mercedes-Benz SL passes its MOT at 86.5%, comfortably above the UK average of 80%, which suggests solid long-term durability for the model. However, nearly a third of these cars (31.6%) have picked up dangerous defects at some point, a concern that warrants a pre-purchase inspection by a specialist.

These SLs are running relatively low mileage for their age—just under 40,000 miles median—yet they still average 1.89 failures per test, indicating that time and wear matter as much as distance on an aging premium sports car. Before committing to one, have a pre-purchase diagnostic run by a Mercedes specialist; these cars demand it.

The 2010 Mercedes Benz Sl has a decent first-time pass rate (86.5%), 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

✅ Good baseline reliability. A 86.5% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 11.1 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 414 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.
