Getting rid of a 2.7 biturbo for a 2.0 single turbo? Me thinks way less maintenance in your future.
Couple things to consider for winter and in general:
1. Did you already tell the dealer not to touch your car? I assume so since you are no newb.
2. scope out the nearest touchless or DIY wash
3. find an insulated and heated enclosure to do your work
4. A heat gun, floss/fishing line and body prep solvent will be helpful in removing the dealership decal and any residue from the transit wrap, you'll likely find the residue on the wheels as well.
5. if you ordered tuxedo black, call back right now and change it to white or silver
I have done new car prep with an ONR wash, but did take it for the most basic touchless first.
