For my most recent cars, i have owned a Mercedes, a BMW and 2-Porsche's as "fun" cars. When I saw this car in the showroom, I had to have it. For a 4-seat convertible, it has a usable backseat. The gadgetry (I have the NAV system) is a bit much to learn, but can be fun to look at. Performace-wise, it is fabulous. I did test drive the equivalent Lexus convertibale and frankly the styling was not for me. This car has it all, styling, performance, comfort, reliablity. Turns a lot of heads, including mine!
The engine and technology of the transmission (the 7 speed automatic), overall styling, handling and performace (it is very, very fast!)
The NAV system is tough to use and the handbook is simply not clear. Of course it is like learning to use any piece of technology, but this is simply too much.
