Isuzu Bighorn (1992)
1992 Isuzu Bighorn
CarHunch analysed 166 real MOT records for the 1992 Isuzu Bighorn. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1992 Isuzu Bighorn has a first-time pass rate of 71.2%, which sits 8.8 percentage points below the UK average of 80%—a meaningful reliability gap that suggests more frequent repairs. Dangerously, nearly a quarter of these vehicles (24.1%) have recorded at least one dangerous defect during MOT testing, which is a genuine safety concern for any prospective buyer.
These 30-year-old Bighorns are running at a median of 152,064 miles, which is typical for their age, but they're accumulating 3.61 failures and 23.4 advisories per test on average—indicating widespread wear across multiple systems. Before buying one, have a pre-purchase inspection focus specifically on the major failure patterns: suspension, braking, and emission systems are likely problem areas given the advisory count, and you should walk away from any example with a history of dangerous defects.
What to check before buying a 1992 Isuzu Bighorn
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.
