Buying Tips for 2004 Rover 45

  • ✓Always check the coolant level and look for signs of overheating; the K-Series engine is unforgiving if it runs dry.
  • ✓Inspect the bodywork for rust, especially around the rear wheel arches, sills, and boot lid hinges.
  • ✓Listen for a whining noise from the manual gearbox, which can indicate worn input shaft bearings.
  • ✓Check the V6 models (if applicable) for timing belt replacement history; it is a very expensive job.
  • ✓Test the electric windows and central locking, as the wiring in the door shuts can become brittle and break.
  • ✓Feel the carpets for dampness, which can indicate leaking door seals or a failing heater matrix.
