Mercedes 240 Td (1984)
1984 Mercedes 240 Td
CarHunch analysed 125 real MOT records for the 1984 Mercedes 240 Td. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1984 Mercedes 240 TD has a 40% first-time pass rate—well below the UK average of 80%—which is a significant warning sign for any prospective buyer, though the complete absence of dangerous defects (0%) means safety isn't the primary concern. The median mileage of 185,307 miles is exceptionally high for a 40-year-old car, suggesting these survivors are heavily used workhorses rather than cherished classics, yet the extraordinarily low failure count (0.01 per vehicle) is genuinely impressive and points to robust engineering once sorted.
These diesels were built to last, and the data suggests that any that are still on the road have proven themselves reliable—but reaching MOT condition in the first place is the challenge. If you're considering one, budget for a thorough pre-purchase inspection and expect some initial remedial work to get it through its first test; after that, longevity is your friend.
What to check before buying a 1984 Mercedes 240 Td
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.
