We got our M3 about three weeks ago, and generally love it. Drives really nice, and has a great set of features. Couple of things we noticed: > The interface has some minor glitches that come and go. Hopefully Tesla will resolve going forward at some point. > The tire noise in the cabin is high for this class of automobile. I've seen some posts on a few ideas to resolve using noise deadening material, but really do not know where to install? Does it go in the trunk only, and will that help the most? Or does one have to tackle the wheel wells? Any thoughts would be appreciated.
