Should I check the MOT history before buying a 1990 BMW 518?

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 1990 BMW 518?

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 1990 BMW 518?

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 1990 BMW 518 reliable?

Based on MOT data from 722 vehicles, the 1990 BMW 518 has a first-time MOT pass rate of 67.7%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

The 1990 BMW 518 is struggling against the odds: a first-time MOT pass rate of 67.7% trails the UK average of 80%, signalling that two in three of these cars arrive at test with faults that need fixing. The good news is that dangerous defects are relatively rare at 12.5%, so structural and safety nightmares aren't the typical story here.

These 518s are averaging 142,763 miles—perfectly normal wear for a 34-year-old car—and when they do fail, it's usually fixable niggles rather than catastrophic issues (1.46 failures per vehicle). Before buying, budget for suspension, lights, and trim work: advisories average 4.9 per car, which points to age-related deterioration that's manageable but persistent. Get a pre-purchase inspection focused on the cooling system and fuel delivery, as older BMWs of this era are known to nickel-and-dime owners with recurring small faults.

The 1990 BMW 518 has a below-average first-time pass rate (67.7% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 8 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 4.9 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 722 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.
