Should I check the MOT history before buying a 2007 BMW 520?

The 2007 BMW 520 diesel falls slightly short of the UK average with a 77.9% first-time pass rate, and a concerning 46.1% of vehicles have recorded a dangerous defect at some point—well above typical levels. This suggests buyers should budget for potential serious repairs and factor in the higher-than-average failure risk.

These cars are averaging 111,000 miles, which is reasonable for their age, but the real story lies in the 3.59 failures and 18.4 advisories per vehicle—indicating persistent, systemic issues beyond simple wear items. Before purchasing, get a pre-buy inspection that specifically covers the electrical and fuel system vulnerabilities common to this model, as the advisory count hints at recurring problems that chip away at ownership costs.

The 2007 BMW 520 has a decent first-time pass rate (77.9%), 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

🔧 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 18.4 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 7,863 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.
