Should I check the MOT history before buying a 1991 Leyland Daf 400 Series Diesel Turbo?

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 1991 Leyland Daf 400 Series Diesel Turbo?

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 1991 Leyland Daf 400 Series Diesel Turbo?

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.

Based on MOT data from 854 vehicles, the 1991 Leyland Daf 400 Series Diesel Turbo has a first-time MOT pass rate of 61.9%, 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 1991 Leyland Daf 400 Series Diesel Turbo?
