Should I check the MOT history before buying a 2008 BMW 523?

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.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2008 BMW 523 passes its MOT at 83%, marginally above the UK average of 80%, but the real concern is that one in three of these cars (33.1%) have recorded a dangerous defect at some point—well above acceptable levels and a serious flag for buyers. This is a vehicle that needs careful inspection before purchase, particularly around brake and suspension integrity.

At 72,600 miles median, these cars are running relatively low mileage for their age, yet they're averaging 2.37 failures and 10.8 advisories per test, suggesting that wear and maintenance issues compound quickly once they emerge. Before committing to a 523, have a pre-purchase inspection focus on the cooling system, suspension components, and brake condition—these are where the failures typically cluster on this model.
