Vacation taken with your car, in which the car is the main reason for the trip, ie car show, bikini car wash marathon, trip to pick up parts.
Looks like a vacation to an unsuspecting person, but really a ploy to drive all over creation to visit car lovers places, such as car shows, car museums, and car auctions.
