Buying Tips for 2010–2011 Subaru Outback Mk4 (BR)

  • ✓The 2.5 petrol is usually the easier car to own long term; diesel examples need far more scrutiny.
  • ✓Operate the electronic parking brake several times, including on a hill, to check for sticking or warning lights.
  • ✓A good BR should feel tight at the front end; vague steering often points to tired control arm bushes.
