Should I check the MOT history before buying a 2004 BMW 320d 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 2004 BMW 320d 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 2004 BMW 320d 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 2004 BMW 320d Sport reliable?

Based on MOT data from 185 vehicles, the 2004 BMW 320d Sport has a first-time MOT pass rate of 68.5%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2004 BMW 320d 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 2004 BMW 320D Sport is a significantly weaker performer than the UK average, with just 37.8% passing MOT first time versus the national 80%—a red flag that reliability issues are commonplace in this cohort. The absence of dangerous defects is a small mercy, but the median CarHunch score of 55 reflects persistent mechanical problems that buyers need to account for.

At 154,845 miles median, these cars are well-worn for their age, and the average of 0.7 failures per test suggests structural wear is catching up with them. If you're considering one, factor in ongoing repair costs and have a pre-purchase inspection cover suspension, cooling system, and electrics—the typical weak points for high-mileage German diesels of this era.
