Should I check the MOT history before buying a 2017 BMW 320d M Sport?

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 2017 BMW 320d M Sport?

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 2017 BMW 320d M Sport?

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 2017 BMW 320d M Sport reliable?

Based on MOT data from 101 vehicles, the 2017 BMW 320d M Sport has a first-time MOT pass rate of 95.5%, 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 2017 BMW 320d M Sport?

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 2017 BMW 320D M Sport has a first-time MOT pass rate of 70%, which is 10 percentage points below the UK average of 80%, suggesting these cars are slightly more prone to test failures than typical. The good news is that dangerous defects are absent from this sample, and the average failure rate of just 0.12 per vehicle indicates most issues are minor when they do occur.

At a median mileage of 72,669 miles, these cars have done genuine work but aren't heavily stressed for their age, which makes the below-average pass rate more of a concern—it suggests inherent reliability issues rather than hard use. Before buying, have a pre-purchase inspection done by a diesel specialist, as the M Sport's sportier setup and the diesel engine's sensitivity to maintenance history mean small issues can compound quickly.
