Carcation

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.
