Buyers do care about a car's paint, especially if it's a rare combination. "You'd be surprised how much that can drive up the value of a vehicle," says Allen, who once bought a Ford Galaxie 500 XL because it was bright pink with a white interior. "It had original paint and the original interior," he recalls. "The car was ordered by none other than Hugh Hefner to give to the Playmate of the Year. That car we sold for four times the amount of what a normal one would have brought. That's a one-of-one car. As far as an investment goes, that's a great one."
