1998 Isuzu Trooper 3.1 Diesel Turbo
CarHunch analysed 133 real MOT records for the 1998 Isuzu Trooper 3.1 Diesel Turbo. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1998 Isuzu Trooper struggles significantly on the MOT: only 40% pass first time compared to the UK average of 80%, which is a major red flag for any prospective buyer. The dangerous defect rate of 11.3% is within acceptable bounds, but the real concern is the sheer number of issues—these vehicles average 1.88 failures and 10.1 advisories per test, pointing to widespread mechanical wear across multiple systems.
At nearly 140,000 miles on the clock, these Troopers are running hard for their age, and the problems stack up: suspension, emissions, and structural corrosion appear frequently in the advisory data. Before buying one, have a trusted diesel specialist conduct a pre-purchase inspection focusing on the turbo system, injectors, and chassis integrity—the MOT pattern suggests those are the real cost drivers for ownership.
What to check before buying a 1998 Isuzu Trooper 3.1 Diesel Turbo
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.
