  • ✓Inspect all four tyre brands and tread depths

Buying Tips for the 2015 BMW X3 (F25)

  • ✓Check all four tyres carefully before trusting any seller who says the xDrive system feels fine
  • ✓Early 20d cars need the same chain diligence as 320d and X1 models
  • ✓Rear springs and front-end steering components are regular UK MOT advisories, especially on M Sport cars
  • ✓Test the electronic parking brake and hill-hold system repeatedly because intermittent faults are easy to miss on a short drive
