What to check before buying a 2001 Trooper
Before buying a 2001 Isuzu Trooper, focus on the areas it most often fails on. Body, structure & corrosion accounted for 15.0% of tests for this year.
- Body, structure & corrosion (15.0% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Lighting & signalling (13.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.5% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
