Should I check the MOT history before buying a 2015 Mercedes Benz Gla?

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 2015 Mercedes-Benz GLA passes its MOT first time at 87.9%, well above the UK average of 80%, which is a genuine strength—but nearly 28% of these cars have recorded a dangerous defect at some point, a higher-than-comfortable figure that buyers should take seriously. Petrol versions perform notably better (91.6% pass rate) than their diesel counterparts (87.5%), suggesting the petrol engines are slightly more robust long-term.

At 52,600 miles median, these cars show typical mileage for their age, yet they're averaging 1.19 failures per MOT, pointing to common issues beyond just wear and tear—and the 7.7 advisories per vehicle mean small niggles are routine. Before buying, get a pre-purchase inspection that specifically flags suspension, braking, and electrical systems, since those dangerous defects don't appear randomly.

The 2015 Mercedes Benz Gla has a decent first-time pass rate (87.9%), 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 87.9% 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 7.7 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 9,250 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.
