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

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 SE?

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 SE?

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 SE reliable?

Based on MOT data from 174 vehicles, the 2004 BMW 320d SE has a first-time MOT pass rate of 71.2%, 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 2004 BMW 320d SE?

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 SE has a first-time pass rate of just 31.8%, less than half the UK average of 80%, making it a significantly unreliable proposition by MOT standards. The good news is that dangerous defects are virtually absent (0%), so what's failing these cars isn't safety-critical—it's typically expensive mechanical and emissions work.

At 157,330 miles median, these are high-mileage examples typical of their age, yet they're still averaging 0.51 failures per test, suggesting the problems aren't simply wear-and-tear on tired engines. Before buying, get a full pre-purchase inspection focused on the diesel particulate filter and emissions system, as these are the chronic failure points on this generation.
