Subaru Legacy GX 4WD (1991)
1991 Subaru Legacy GX 4WD
CarHunch analysed 461 real MOT records for the 1991 Subaru Legacy GX 4WD. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1991 Subaru Legacy GX 4WD is extraordinarily unreliable by modern standards—only 3.8% pass their MOT first time, compared to the UK average of 80%. These 33-year-old vehicles are essentially worn-out, with a median mileage of 129,689 and virtually no dangerous defects recorded (0.4%), suggesting that those still on the road have simply been driven into the ground rather than abused.
At this age, the low failure and advisory counts (0.05 and 0.1 per vehicle respectively) reflect survivorship bias—only the toughest examples remain registered, not that the model is particularly durable. If you're considering one of these as a classic or weekend project, budget heavily for comprehensive mechanical work and treat the first MOT as a starting point for repairs, not a sign the car is roadworthy.
What to check before buying a 1991 Subaru Legacy GX 4WD
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.
