Should I check the MOT history before buying a 2003 BMW 545?

The 2003 BMW 545 falls just below the UK average with a 78.3% first-time pass rate, but the real concern is that 44.4% of these cars have recorded a dangerous defect at some point—nearly double the typical rate—making pre-purchase inspection essential. With an average of 3.57 failures per vehicle and 19.3 advisories, this is a high-maintenance proposition even among nearly 21-year-old cars.

At 87,527 miles median mileage, these examples have been driven moderately for their age, so don't expect wear-and-tear to be the sole explanation for the troubling safety record. Budget carefully for electrical and cooling system work (common BMW weaknesses), and always get a full pre-purchase inspection by a specialist; this cohort's dangerous defect history suggests corner-cutting on maintenance has been common among previous owners.

We have limited data for the 2003 BMW 545 — treat the figures below as indicative rather than definitive.
