Honestly - I'm getting tired of the this M LED LCI BS that BMW has been doing for years now. Just put them on at the beginning and stop this marketing nonsense.
Example
e9x M3 No Led tails at launch.
e9x M3 LCI Led tails.
F8x M3/M3 No Led tails at launch.
F8x M3/M3 LCI Led tails at launch.
So did BMW lose the LED tech drawings between models?
