Don't sign up for tire/wheel warranty. Contact discount tire today and buy their road hazard. some tires like Dunlop/Michellin come with road harzard. Bridgestone dueler's didn't come with it. Call your SA and ask what brand of tires it has on. The car comes with a CD which tells you what brand has road hazard and which don't - the dealer won't tell you this.
Don't buy paint sealant warranty.

There are some things you can do even later...main thing check paint/seats etc..once out of the door..all the damage belongs to you. All the navi, bluetooth, BMW assist can be done later also and if not working will be fixed under warranty.
