Buying Tips for the BMW 4 Series (G22/G23/G26)

  • ✓Check the front grille area carefully for any stone damage or minor impacts, as the radar sensors are very exposed
  • ✓On M440i models, monitor the coolant level closely; the B58 engine is generally reliable but can have slow seeps
  • ✓Test the convertible roof (G23) and the Gran Coupe (G26) frameless windows for smooth, silent operation
  • ✓Verify the latest iDrive 7 or 8 software is installed to avoid known navigation and connectivity bugs
