Buying Tips for the 2014 Subaru Forester Mk4 (SJ)

  • ✓If you want a low-risk car, a well-serviced petrol is far easier to recommend than a late diesel.
  • ✓On CVT cars, look for fluid changes around every 50,000 miles even if a seller calls the oil "sealed for life".
  • ✓Test the air conditioning from cold and after a long idle, as weak compressors are a known Forester SJ annoyance.
