Aston Martin One-77 — $1.4 million

To Aston Martin, aesthetics are as important in the design of its newest creation as are function and performance. To that end, the One-77 (so named because only 77 of these cars will be made) has what's called a monocoque design, which means the body of the car is crafted out of one big piece of carbon fiber — common in race cars, but rare in street cars. It has a level of customization light years beyond color preference and transmission type: The suspension isn't fine-tuned until the car is delivered to its owner. As Car and Driver magazine put it, "The One-77 is what happens when an automaker builds a car without ever saying 'no' to its engineers."
