20. 2012 Maserati GranTurismo MC
There's only one car on this list that's currently for sale, and it's easy to see why. The GranTurismo's Jason Castriota-penned design was an instant classic, and is aging better than anything else on the market. We think this exotic, yet elegant, design will be gracing the auction block at the Pebble Beach Councours in 2070.
