Should I check the MOT history before buying a 2004 BMW 5 Series?

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 5 Series?

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.

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.

The 2004 BMW 5 Series passes its MOT at 79.4%, marginally below the UK average of 80%, but the real concern is that nearly one in three of these cars (32.9%) has recorded a dangerous defect at some point—well above acceptable. Diesel versions are slightly more problematic, with a 78.7% pass rate compared to petrol's 80.5%.

At nearly 106,000 miles median, these cars are well-used for their age, yet they average 3.13 failures and 16.4 advisories per test, suggesting complexity and wear catching up fast. If you're considering one, budget for serious mechanical attention and expect repair bills to be steep; a pre-purchase inspection by a BMW specialist is non-negotiable rather than optional.

The 2004 BMW 5 Series has a decent first-time pass rate (79.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 16.4 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,893 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
