Should I check the MOT history before buying a 2020 Mercedes Benz Gla 200 Amg Line Edition + A?

This GLA 200 is a genuinely reliable proposition: a 92.5% first-time pass rate comfortably beats the UK average of 80%, and only 9.2% have ever recorded a dangerous defect, which is low enough that safety isn't a concern for the typical buyer. Petrol engines dominate this cohort, and they're performing well across the board.

At 27,348 miles average for a 2020, these cars are running well within normal mileage expectations, and the 0.29 failures per vehicle tells you that when they do fail their MOT, it's usually minor stuff—the 2.3 advisories per car suggest wear items rather than structural problems. If you're shopping this model, get a pre-purchase inspection focused on the minor trim and electrical niggles that seem to crop up, but mechanically you're looking at a solid bet.

The 2020 Mercedes Benz Gla 200 Amg Line Edition + A passes its MOT first time more often than most UK vehicles (93.4% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

For context

✅ Good baseline reliability. A 93.4% 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 2.3 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 2,050 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.
