Buying Tips for 2001 Toyota Avensis Mk1 (T22)

  • 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.
