This is the first time I'm planning on participating in this event. That is why I'm waiting for Germany to chime back in. Don't worry about car, wash, wax, vaccum, and your good. My car has almost 29K miles. You will have the usual wear and tear. I'm going for the Christmas cheer and see cool cars. Maybe meet some other owners. There is another web site for Xfire owners and many are in the valley. They haven't been hugely active but usually get together once a year for a weekend cruise. Geat people, fun time.
