Essential Pre-Purchase Step

Buying a used Toyota Avensis Mk1 (T22)? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Toyota Avensis Mk1 (T22) Buyers

✓Check thoroughly for structural rust, especially around the rear subframe, sills, and wheel arches, as this kills more Mk1s than mechanical failure.
✓Inspect the service history to ensure oil changes were done; neglected early 1.8 engines can burn oil.
✓Verify the clutch action on manual models, as replacing it can exceed the value of the car.
✓Listen for worn suspension components, particularly knocking from the front anti-roll bar links and bushes.
✓Check all interior electrics, including the heater blower and window regulators, which can fail with age.
✓Examine the condition of the brake lines and exhaust system for excessive corrosion during a pre-purchase inspection.
