Picked up my M3LR yesterday at Fremont. The car comes with mobile charger and matrix lights. HOWEVER, I do found another M3LR of VIN 241XXX have the "old" premium lights, which sort of confirms that some batches of M3 were made w/o matrix lights. Another useful information is, Tesla held up my car for 3 days, since I was out of town; 3 days range is the maximum.
Going back to the car, the building quality of my M3 is very good. I did not find any defects during inspection. BUT, I also looked around at other M3s on the parking lot, and some of them have small defects, e.g., obvious part nonalignment or window tape issue. In general, the car is amazing: fast acceleration, immersive sound system, even the suspension is not that tough, even I have 19' tires. Interestingly, it just took me several miles to get used to the one-pedal driving.
Anyways, I completely graduate today!! Good luck to everyone!!!
