Should I check the MOT history before buying a 2006 BMW 550?

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.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2006 BMW 550 passes its MOT first time at 80.2%, matching the UK average almost exactly—but nearly 40% of these cars have recorded a dangerous defect at some point, which is significantly high and suggests real reliability concerns for buyers. The petrol engine's inherent complexity shows through in the numbers: these cars average 3.38 failures and 17.6 advisories per test, indicating they're prone to the kind of expensive issues BMW owners often face.

With a median mileage of 85,864 miles for a 2006 model, these cars have been driven fairly hard, yet that high dangerous defect rate isn't mileage-dependent alone—it's symptomatic of aging German engineering and cost-intensive maintenance. Before buying, have any prospective 550 inspected by a BMW specialist to check the suspension, cooling system, and electrical gremlins, and budget seriously for repairs or walk away if the service history is incomplete.
