BMW 518 (1980)
1980 BMW 518
CarHunch analysed 469 real MOT records for the 1980 BMW 518. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1980 BMW 518 has a first-time pass rate of just 50%, significantly below the UK average of 80%, making it a notably unreliable proposition for buyers. Dangerous defects have appeared in 20% of the vehicles tested, which is a genuine safety concern and a red flag when considering purchase.
These cars are averaging over 90,000 miles, which is reasonable for a 44-year-old model, but the minimal failure and advisory data (0.01 failures and effectively zero advisories per vehicle) suggests that either these vehicles are getting scrapped or heavily restored before MOT rather than limping through with minor issues. Before committing to one of these classics, insist on a thorough pre-purchase inspection focusing on brakes, suspension, and electrical systems—the areas most likely to trigger that dangerous defect rating.
What to check before buying a 1980 BMW 518
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
