Also, if there is any defect, especially if you ordered a black car, you can reject it easier there. I personally would have a hard time rejecting it when they drove it to my house. Also, insist on inspecting the car before signing. I believe there are significantly less defects now than earlier but black shows even the slights paint defect.
I also so worried that I to tried and decide what level of level of defect would I reject ahead of delivery. Thank god I had no defect except for two tiny scratches on the headlight and tail light, I ordered Pearl white, I decided to live with it. I didn’t want them to try and polish it out and remove the protective coating. Months afterwards,I found a slight frump misalignment. I adjusted to rubber stops, it looks better but not sure if I want it looked at. I since looked at some Acura’s closely and found they have misalignment on the hoods.
I think I worried too much with all the old comments on the cars defects, you should relax and enjoy your M3 delivery. I can’t believe how much of a joy the M3 is even with the nitpicking.
