The 2008 BMW 520 matches the UK average first-time pass rate at exactly 80%, which is respectable for a car now 16 years old, but the headline concern is that 33.7% of these vehicles have recorded a dangerous defect at some point—well above the typical threshold and a genuine safety consideration for any buyer. With a median mileage of 103,472 miles, these cars have been driven normally for their age, yet they're averaging 2.71 failures per test and accumulating 13.5 advisories, suggesting ageing components and wear that compounds quickly.
Most examples here are diesel (8,500 of 8,566), and they hold the same 80% pass rate as petrol variants, so fuel type isn't a differentiator. If you're serious about buying one, budget for suspension, cooling, and electrical work as routine maintenance, get a full pre-purchase inspection to check specifically for suspension and brake defects (the most common failure points in this era), and walk away if the service history is patchy—these Beamers reward consistency and punish neglect.
The 2008 BMW 520 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.
These stats describe 8,566 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.

Brake pipes, sills and subframes are the key areas on a vehicle this age — structural rust is hard to spot without getting underneath. A mechanic will check all of this before you commit, and give you a concrete basis to negotiate on price.
