Think it's possible for an everyday car at a dealership to one day become a collectible car worth millions? Vehicle valuation specialists, Black Book, analyzed several affordable cars that were once purchased modestly at MSRP and eventually became great collectibles. Here is the list, compiled by Black Book:

The 1971 Plymouth Barracuda was once purchased at an asking price of $4,296, and today it has a current value of $2.5 million, a 58000% increase in value over time. The 1967 Shelby Cobra was once purchased for $7,500 and has a present day value of $1.3 million, a 17000% increase. Other popular models in the list include names such as Eldorado, Corvette, Bonneville, Thunderbird, and Mustang GT.

"What makes a car a collectible over time includes any number of factors that include popularity, pop culture, and production volume," said Eric Lawrence, Director of Specialty Products at Black Book. "Many people think today's uber-expensive vehicles always came with a hefty price tag, but these vehicles show that's clearly not the case."

Black Book attends wholesale vehicle and specialty vehicle auctions around the country each day and week, recording and publishing valuations in real time for a variety of automotive professionals.
