Should I check the MOT history before buying a 2006 BMW 520d 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 2006 BMW 520d 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 2006 BMW 520d 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 2006 BMW 520d M Sport reliable?

Based on MOT data from 147 vehicles, the 2006 BMW 520d M Sport has a first-time MOT pass rate of 70.1%, 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 2006 BMW 520d 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.

This 2006 BMW 520D M Sport is a serious reliability concern: only 21.9% pass their MOT first time, compared to the UK average of 80%. Buyers should expect significant repair costs, with the average vehicle racking up 0.69 failures per test.

At nearly 160,000 miles, these cars are running high mileage for their age, which partly explains the struggle—but the pass rate is catastrophically low even accounting for that. If you're considering one, factor in substantial servicing and parts replacement before purchase, and get a full pre-buy inspection from a BMW specialist rather than relying on MOT history alone.
