Buying Tips for 1995–1999 Rover 400 Series

  • ✓Rust is the biggest killer; check the rear sills, wheel arches, and the floorpans thoroughly.
  • ✓On K-Series models, demand proof of head gasket replacement and check the coolant for signs of oil contamination.
  • ✓If buying a Honda-engined automatic, ensure the gearbox fluid has been changed and shifts smoothly.
  • ✓Inspect the interior fabric, particularly on the door cards, where the material frequently sags or peels.
  • ✓Check the operation of the sunroof (if fitted) for leaks and ensure the drainage tubes are clear.
  • ✓Test the heater matrix; if it smells sweet inside the cabin when the heater is on, it is leaking.
