Buying Tips for the 2017 BMW i3 (I01)

  • ✓On REx models, ensure the petrol engine starts and runs smoothly; many are never used and can seize or corrode internally
  • ✓Check the custom narrow Bridgestone Ecopia tyres for wear; they are expensive and can wear quickly on the rear
  • ✓Inspect the CFRP door sills and the plastic body panels for any cracks or structural damage
  • ✓Verify the high-voltage battery capacity via the hidden service menu to ensure it hasn't degraded excessively
