Starting price: $301,750
5-year total: $364,471

What pushes the Black Series up the price ladder from the SL65 AMG is the wide use of carbon-fiber body parts and some under-the-hood enhancements.

Capable of reaching 60 miles per hour from a standstill in just over four seconds, the S65 AMG combines opulent interior appointments with outrageously aggressive performance.

5-year total: $153,588

The "L" in its name refers to this luxury sedan's stretched wheelbase, while the "W12" indicates it packs the potent 450-horsepower, 6-liter, W-12 engine under its hood.

Although it doesn't possess the amount of high-end bric-a-brac many of the other entries on this list do, pound for pound and dollar for dollar it may just be the best sports car in the world.
8. Porsche Cayenne Turbo S
Starting price: $125,775
5-year total: $138,613
Cost per mile: $1.85
The only SUV on this list, the Cayenne Turbo S packs Porsche performance into an off-road-capable all-wheel-drive uber package. Turning all four wheels is a 550-horsepower, 4.8-liter, twin-turbo V-8.
