2011 Porsche Cayman

Base MSRP $51,900

Although the Cayman might not be quite as fast as other exotics, it provides one of the best sports-car driving experiences, with critically lauded steering and handling and costs less than Porsche's own flagship 911 Carrera. With good cargo space, respectable fuel economy and decent driver and passenger comfort, it makes a respectable commuter than most other performance-oriented machines.
