Should I check the MOT history before buying a 1986 Daimler 4.2 Auto?

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 1986 Daimler 4.2 Auto?

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 1986 Daimler 4.2 Auto?

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 123 vehicles, the 1986 Daimler 4.2 Auto has a first-time MOT pass rate of 73.2%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 1986 Daimler 4.2 Auto?

This 1986 Daimler 4.2 Auto has a first-time MOT pass rate of 73.2%, which sits 6.8 percentage points below the UK average of 80%, suggesting these cars demand more attention to maintenance than typical. The dangerous defect rate is mercifully low at 1.6%, so while reliability is slightly below average, serious safety issues are rare.

At an average mileage of 87,070 miles for a vehicle now nearly 40 years old, these cars show modest use overall, which explains the modest failure rate of 0.19 per vehicle—most are failing on minor issues rather than structural problems. If you're considering one, factor in that it will likely need at least some remedial work before passing its next test: check the full MOT history carefully and budget for pre-purchase inspection by a specialist in classic British cars.
