Buying Tips for 2003 Honda Accord Mk7

  • A petrol manual is the easy recommendation; diesel cars need believable evidence of clutch work and careful maintenance.
  • On 2.2 i-CTDi cars, start from cold and listen for unusual diesel clatter or exhaust fumes from the manifold area.
  • Make sure the ABS and VSA lights go out properly and inspect the rear brakes because caliper drag and pad wear are common.
