This is a 4 door race car. Performance and handling are as good as the Porsche I used to own. The difference is that this is an everyday driver. I don't understand the complaints about the iDrive. With a little effort, I find it very intuitive. The SMG is the same - with some experience, it becomes second nature.
Bluetooth and voice command are great. Seats are very comfortable. The active seats are a nice touch for extra cornering support. Overall aggressive styling may be copied by lesser vehicles, but the engine and suspension are unique and the best.
Interior could be improved (Audi has the lead here).
