Should I check the MOT history before buying a 2020 BMW X6 M50d Auto?

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.

What corrosion should I look for when inspecting a 2020 BMW X6 M50d Auto?

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.

How are tyres and brakes typically on a 2020 BMW X6 M50d Auto?

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.

Is the 2020 BMW X6 M50d Auto reliable?

Based on MOT data from 190 vehicles, the 2020 BMW X6 M50d Auto has a first-time MOT pass rate of 90.1%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2020 BMW X6 M50d Auto?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2020 BMW X6 M50D is performing above the UK average with an 84.9% first-time pass rate versus the national 80%, suggesting these diesel SUVs are holding up reasonably well mechanically. However, 11.6% have suffered dangerous defects, which is notably elevated and worth investigating on any used example you're considering.

At nearly 40,000 miles, these vehicles are showing the mileage you'd expect for their age, and the low failure rate of 0.39 per vehicle indicates most don't have significant structural or safety issues. Before committing to purchase, have an independent BMW specialist conduct a pre-buy inspection focusing on the diesel engine's EGR and DPF systems, as these are common problem areas on turbocharged units at this mileage.
