you can't change the dealer, so you are going to have to drive up and get it. That is what they made me do. I called smart and they said I would be able to change it, but when it came in, it was delivered to Ft. Worth instead of Houston (300 mile drive). Yeah that was one thing that kinda made me mad.
I dont think the "home dealer" is going to matter. Just take it wherever is closest. If changes in the system need to be made, i am sure they will make them, but i can't imagine what difference it would make.
