Buying Tips for 2019 MINI Hatch (F55/F56)

  • B38 and B48 engines are generally far better than the earlier Prince engines, but upper engine mounts are almost a service item on some cars
  • Check the oil-filter housing, coolant hoses, and expansion tank area for small leaks before they become bigger jobs
  • Run all infotainment functions and look for screen delamination or rebooting on early cars
  • Large-wheel cars can feel crashy when front bushes and top mounts are worn
