Buying Tips for the 2021 BMW iX (I20)

✓Test the complex iDrive 8 system and the 'Shy Tech' interior buttons (integrated into the wood trim) for responsiveness and software lag.
✓Check the electrochromic panoramic glass roof (which turns opaque at the touch of a button) to ensure it transitions evenly without patchy spots.
✓Inspect the carbon-fibre reinforced plastic (CFRP) door shuts for any signs of damage or cracking, as structural repairs are incredibly specialized.
✓Verify the charging flap operates correctly and the car achieves its claimed rapid charging speeds without throwing errors.
✓Listen to the air suspension over rough roads; the iX is very heavy, so worn bushes or failing struts will cause noticeable knocking.
✓Ensure the self-healing polyurethane front grille isn't deeply gouged, as the embedded radar sensors require a clear line of sight to function.
