Should I check the MOT history before buying a 1991 Isuzu Trooper Lwb Turbo Diesel?

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 Isuzu Trooper Lwb Turbo Diesel?

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 Isuzu Trooper Lwb Turbo Diesel?

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.

Is the 1991 Isuzu Trooper Lwb Turbo Diesel reliable?

Based on MOT data from 853 vehicles, the 1991 Isuzu Trooper Lwb Turbo Diesel has a first-time MOT pass rate of 62%, 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 Isuzu Trooper Lwb Turbo Diesel?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 1991 Isuzu Trooper diesel is substantially less reliable than the UK average: it passes MOT first time just 62% of the time versus the national 80%, meaning roughly one in three will need work before passing. The dangerous defect rate of 2.7% is low, so serious safety issues aren't a widespread concern, but the overall pass rate deficit is a real reliability red flag.

At around 141,000 miles median, these vehicles are naturally tired for their age, yet they're generating only 0.21 failures per vehicle on average—suggesting they fail not because of catastrophic problems but because small issues accumulate. Before buying, budget for pre-purchase inspection and expect maintenance during ownership; the relatively low failure count means problems tend to be addressable rather than terminal, but the low pass rate shows they need active care to keep road-legal.

The 1991 Isuzu Trooper Lwb Turbo Diesel has a below-average first-time pass rate (62% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
