Should I check the MOT history before buying a 1999 BMW 520i 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 1999 BMW 520i 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 1999 BMW 520i 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 1999 BMW 520i SE reliable?

Based on MOT data from 104 vehicles, the 1999 BMW 520i SE has a first-time MOT pass rate of 69.1%, 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 1999 BMW 520i 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 1999 BMW 520I SE is a genuinely rare find—only 4.7% pass first time compared to the UK average of 80%, which means nearly every one of these cars will need work before it clears MOT. The good news is that dangerous defects are essentially non-existent (0%), so you're not looking at safety-critical failures, just the accumulated wear and tear of a 25-year-old German saloon.

At an average of 147,125 miles, these cars are typically high-mileage examples, which explains why they're hitting MOT issues so consistently. The fact that failures average just 0.06 per vehicle with zero advisories suggests the problems are straightforward and predictable—likely suspension, exhaust, and trim components rather than engine or gearbox nightmares. Before you buy, get a pre-purchase inspection focused on cooling system integrity and rubber bushings, as these are where older 5-Series typically bleed money.
