Buying Tips for 2002 Toyota Yaris Mk1

  • Thoroughly inspect the sills, floor pan, and rear suspension mounting points for severe rust, as this is the primary reason for scrapping.
  • The 1.0 and 1.3 VVTi engines use a timing chain; listen for excessive rattling on a cold start which indicates stretched chains or worn tensioners.
  • Check the digital dashboard display; missing segments or a flickering screen indicate failing capacitors that can be fiddly to repair.
  • Look for signs of water ingress in the boot well and rear passenger footwells, usually caused by failing door seals or blocked drains.
  • Test the clutch bite point; a high bite point or heavy pedal suggests an impending replacement, which can cost more than the car is worth.
  • Ensure the heater matrix functions correctly on both hot and cold settings, as replacing it is a labour-intensive dashboard-out job.
