I picked up my daughter's M3 on Friday, and drove to Montreal that evening. my only issue is road noise.
Also on a long stretch of the 401 between Oshawa and Cobourg, it felt as if one of the wheels was loose and going to come off. I slowed down and was looking for a safe spot to stop the car and check, but then the pavement surface changed and the rattling disappeared.
Compared to my 2015 MS, this car is way more fun to drive. Unless Tesla updates the S soon, I’ll be opting for the P3D come December.
