Should I check the MOT history before buying a 2015 BMW 640d M Sport 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 2015 BMW 640d M Sport 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 2015 BMW 640d M Sport 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.

Based on MOT data from 124 vehicles, the 2015 BMW 640d M Sport Auto has a first-time MOT pass rate of 94.2%, 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 2015 BMW 640d M Sport Auto?

This 2015 BMW 640D has a first-time MOT pass rate of just 26.5%—dramatically below the UK average of 80%—which is a serious red flag for potential buyers. The good news is that dangerous defects are absent from this cohort, but the reliability verdict is unmistakable: this model is consistently failing its MOT tests.

With a median mileage of 57,915 miles for a nine-year-old car, these examples are relatively low-mileage, yet they're still struggling to pass inspection, which suggests the failures aren't simply wear-and-tear related to high usage. Before buying one, get a full pre-purchase inspection from a specialist diesel mechanic who knows BMW 640Ds well—the pattern here points to systemic issues rather than isolated problems.
