Should I check the MOT history before buying a 1989 BMW 525 I 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 1989 BMW 525 I 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 1989 BMW 525 I 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.

Do I need an HPI check when buying a 1989 BMW 525 I 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.

1989 BMW 525 I SE

CarHunch analysed 1,197 real MOT records for the 1989 BMW 525 I SE. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1989 BMW 525 I is in severe trouble: just 10% of these cars pass their MOT first time, compared to the UK average of 80%. With a petrol pass rate of 0%, every single petrol example tested failed its MOT, and no dangerous defects were recorded—meaning failures are scattered across multiple minor issues rather than one critical problem.

At nearly 95,000 miles on average, these 35-year-old cars are carrying genuine age-related wear, which explains the systematic test failures. Before buying one, budget for a full pre-purchase inspection focusing on suspension, brakes, and electrical systems, then expect to spend serious money bringing it to roadworthy condition.
