Should I check the MOT history before buying a 2007 Mercedes Benz Gl 320?

Moderate sample. 496 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2007 Mercedes-Benz GL 320 matches the UK average pass rate at 80.1%, but there's a serious caveat: 35.1% of these vehicles have recorded a dangerous defect at some point, well above the typical threshold and a genuine safety concern for buyers. This large seven-seater demands careful pre-purchase inspection and full service history verification before committing.

These GL 320s average 88,450 miles for their age, which is typical, but they're racking up 3.16 failures and 20.3 advisories per test—substantially above what you'd expect from a premium brand. The median CarHunch score of 50 reflects this: factor in the high dangerous defect rate and expect significant maintenance bills, particularly around suspension, cooling, and emissions systems on older examples.

The 2007 Mercedes Benz Gl 320 has a decent first-time pass rate (80.1%), 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 20.3 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 496 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.
