I have the same seats that came with the ZSP then and now; in 08 and 11, the comfort seats with the gazillion-way adjust are standard. I just find the rear part of the seat cushion less padded in my 11 than in my 08. The rest is about the same, very nice feel. Luxury sport.Huh. I wonder if most people feel this way. I like to feel more like I'm sitting in a chair than sitting on the floor. That's why I'd never buy a sports car.
I find the seats in my F10 to be more comfortable. I had the "sports seats" in my E60 (or whatever they called them), and have the comfort seats now. Maybe you didn't go from sports to comfort?
