The legendary maker of some of the best luxury cars you can buy has had a reputation of exemplary engineering since its introduction in 1906. While the vehicles are still built in England, Rolls-Royce is actually owned today by BMW. The most expensive Rolls-Royce is the Phantom; Phantom pricing starts at more than $450,000. There's also an SUV, the Cullinan. It's named after—appropriately enough—the largest diamond ever found.
