Should I check the MOT history before buying a 2009 BMW 523?

The 2009 BMW 523 passes its MOT at 83.1%, slightly above the UK average of 80%, which is reassuring—but one in three of these cars has experienced a dangerous defect at some point, a significantly higher concern rate than typical. This suggests the model has some systemic weaknesses that can develop into serious safety issues.

At 71,000 miles median, these cars are showing fairly typical wear for their age, yet they're averaging 2.51 failures and 11.6 advisories per test, indicating persistent minor and moderate problems across the board. If you're considering one, budget for regular maintenance beyond routine servicing and have a pre-purchase inspection focus specifically on suspension, braking, and electrical systems where BMWs of this generation commonly fail.
