Want to buy a reasonably priced car that stands a chance of becoming a classic? You start by acquiring something that is hot and sporty and not produced in the hundreds of thousands.
Black Book, the used-car guide, examined several classics that were once accessible to the average buyer and now command prices hundreds of times higher than when they were produced.
Take, for instance, a 1971 Plymouth Barracuda convertible, which had a suggested retail price of $4,296 when it hit showrooms. That same car today is valued by Black Book at $2.5 million, a 58,000 percent increase.
Other classics, including the 1967 Shelby Cobra, 1965 Ford Mustang GT and 1959 Cadillac Eldorado, have gone from affordable back in the day to collector's items that fetch more than 20 times their original sticker prices.
"A Dodge, a Plymouth, a Mustang -- these were not the Lamborghinis of their day," said Eric Lawrence, Black Book's director of specialty products.
