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

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 Es?

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 Es?

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 Es reliable?

Based on MOT data from 248 vehicles, the 2004 BMW 320d Es has a first-time MOT pass rate of 68.3%, 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 Es?

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 ES is a serious reliability concern: just 31% pass on the first attempt versus the UK average of 80%, meaning nearly seven in ten fail their MOT. The good news is that dangerous defects are absent from this cohort, but the gap between this car and the average is substantial enough that you should expect repair costs during ownership.

At 158,000 miles median, these cars have been driven hard and show it—the 0.57 average failures per vehicle suggest recurring issues rather than catastrophic single problems. Before buying, get a pre-purchase inspection focused on the diesel engine, transmission, and suspension, as those failures will drive your running costs significantly higher than you'd expect from a 20-year-old saloon.
