Should I check the MOT history before buying a 2018 Mercedes Benz GT?

Moderate sample. 318 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2018 Mercedes-Benz GT passes its first MOT attempt 95.2% of the time, well above the UK average of 80%, which signals strong build quality and reliability from this cohort. Dangerous defects are relatively uncommon at 10.1%, so safety isn't a red flag for prospective buyers.

These cars are running light for their age at an average of 14,612 miles, which likely explains the excellent pass rate and also suggests they're cherished rather than hard-driven. The low failure rate (0.29 per vehicle) combined with moderate advisories (1.7) means routine maintenance rather than major repairs tends to be the story—but do budget for electrical and suspension checks as part of ownership, as this is typical for sports cars of this calibre.

The 2018 Mercedes Benz GT passes its MOT first time more often than most UK vehicles (95.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 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 95.2% 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 1.7 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 318 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.
