The Quattroporte holds the No. 10 spot on the list because it was one of the first near-$100,000 cars to really sell in significant quantities, leading other automakers to believe they could get away with attaching six-figure price tags to fancy cars. It's still one of the most inexpensive Italian exotic cars you can buy, at $110,600, and this year it sports a traditional automatic transmission. Plus, you can feel like one of the guys from "Entourage." At the same time, though, that show illustrates how quickly trends can change. The "Entourage" crew moved on from the Quattroporte to Aston Martins and the Mercedes-Benz S-Class faster than they changed clothes.
