This home's 15-car "show garage" looks like something out of Chitty Chitty Bang Bang. Classic cars sit atop a red-and-white checkerboard floor, framed by vintage gas pumps. There are also matching red-and-white walls and museum-grade lighting. Located in exclusive Paradise Valley outside Phoenix and Scottsdale, the home also features six bedrooms -- including four children's bedroom suites that each have their own jacuzzi, shower and walk-in closet. The house also boasts a wine room and a nine-seat theater, while the grounds host a tennis court, swimming pools, a guest house and a second "bus garage." You can see all of the details here.
