This will be my first winter with my 08 m3, and I'm wondering if I should rust proof it. I don't really want holes drilled in the car, and so I'm kind of hesitant on following through.

Also, I think most of the material is galvanized, so it doesn't rust easily?

I use it as my everyday car, and i'm leaving it outside in the snow all the time. Has anyone experieced a problem doing so? or would anybody have any input if i'm gonna completely ruin the car doing so.

Thanks alot for all the input!

In my opinion, you don't need it (the car's got a 10-year no rust warranty). If you're concerned about the long run, use a car wash that washes salt and dirt from under the car. I do that every couple of weeks during the winter.

Just take the car over the the touchless wash - or the quarter carwash once a week and spray the undercarriage.
