With Baz Luhrmann's rock ‘n’ roll biopic "Elvis" storming the box office, interest in The King’s music and life — along with one particular brand of classic car — has skyrocketed. Elvis had a soft spot for Cadillacs, owning upwards of 200 Caddies in his tragically short lifetime, although the actual number is impossible to determine since he regularly gave them away to friends and family.

Standing out among Elvis' personal collection was a custom solid gold 1960 Cadillac Series 75 Fleetwood limo, which included a turntable stereo and TV, a full bar, and a few dozen coats of diamond dust Pearl paint. Adjusted for inflation, the custom caddy would have set Elvis back around half a million dollars in today's money. The car can be seen at the Country Music Hall of Fame.

Elvis fans, eager to get their hands on a Cadillac that was once owned by The King himself, will likely have to spend more than a million dollars. According to Mecum Auctions, a 1972 Cadillac Sedan DeVille station wagon that General Motors custom-built for Elvis was put up for auction at Kissimmee in 2011, and then reappeared on eBay in 2015 for a staggering $1.5 million.
