Buying Tips for the MG MG3

  • Listen for a rattle from the engine on cold starts, which can indicate timing chain stretch.
  • Inspect the paintwork carefully, especially on the roof and around the windscreen for signs of early corrosion.
  • Check all infotainment functions; the system is known for being laggy and occasionally freezing.
