Leyland Daf 400 Series (1993)
1993 Leyland Daf 400 Series
CarHunch analysed 186 real MOT records for the 1993 Leyland Daf 400 Series. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1993 Leyland DAF 400 Series is a serious reliability concern—only 21.4% pass their MOT first time, less than a quarter of the UK average of 80%. The petrol variants fare no better at 17.8%, and while dangerous defects are relatively uncommon at 7.5%, the sheer scale of failures means this is a vehicle that will cost you money.
The median mileage of 68,448 miles is low for a 30-year-old vehicle, yet these survivors are still failing with an average of 0.68 failures and 2.6 advisories each—suggesting age and condition, not wear, are the culprits. If you're considering one, budget for serious mechanical work before and after purchase, and have a pre-purchase inspection by a specialist in light commercial vehicles.
What to check before buying a 1993 Leyland Daf 400 Series
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.
