Driving fun and fuel economy aren't always oxymorons
9th: 2008 Porsche Boxster – $45,800 base price
Porsche's Boxster and Cayman have a common platform, yet the Boxster costs a little less, landing it higher on our list here. Both cars offer up a great driving experience, and thanks to the thrifty 2.7-liter flat-6 engine in both, they get good gas mileage out of each gallon of premium fuel. Take your pick: wind-in-the-hair fun, or the snarky good looks of the Cayman. Either way, it's pure Porsche.
