 I previously owned an '07 Cayman S.  This car is a beautiful compromise between a sports car and a luxury car.  It is tight, fast, and comfortable.  It is easy to drive.  The gas mileage is surprisingly good if driven conservatively.  I was leery about the run-flats, but I have to say I don't notice a harsh ride or excess noise (especially compared to the ride of the Porsche in sport mode, with conventional tires).  The options do push the price up.
