I've been reading the last few days about people wanting to put clear bra's on their M3's to preserve the paint. This was something I really had not considered before, but then I've never had a brand new car and tended to just think the car was for getting from a to b. With the M3, I'm in a different place as this is the first time I'm getting a car that I feel excited about owning. So far I've been looking at getting a spare set of wheels for snow tire swapping and now am thinking about at least getting the front of the car covered with 3M or Xpel. What other things are people thinking of doing to 'preserve' their M3 once they have it in their hands? Are their upgrades or changes that anyone is thinking they would make to the car? I'm curious to know if people think the additions/changes are must do's to keep the car in good condition for a long time as well.
