Elvis's Cadillac station wagon (VIN 6D49R2Q163176) is cream with a black vinyl top, leather interior and has a small gold plaque on the passenger side door engraved with "TCB." It was auctioned by Guernseys on October 7th-8th 1999 at the MGM Grand Hotel in Las Vegas for $34,500. It has four regular doors and the fifth door on the back opens two different ways.
The car actually started its life as a 1972 Cadillac Fleetwood sedan that was shipped from the factory in Detroit to the American Sunroof Company where it was converted in to an Estate Wagon.
