Runflat tires do cause a bit of hard ride. I hit a pothole without seeing it and it bent the rim very easily. Dealer wanted $600 for just the rim. I average 18 MPG as it stated I would. No big deal coming from a Tundra with 13 MPG. Convertible parts are very expensive. Overall I do enjoy driving the car alot and will probably keep it until it dies out on me. I haven't had any major mechanical issues at all with the car.
Hideaway navigation and CD player. Hard top convertible. 288 HP Engine.
My suggested improvements have already been made on the newer models except for one. A/C vented seats!!!
