please do not say that they are "comfy as hell", i don't mean to crap on your thread but i have exactly those seats and i love 'em, but i would not call them exactly comfortable. I just don't want anyone to be mislead.
Getting in/out of them is quite a chore untill you get used to them. And my back was hurting for the first 3 months of driving in them. Now my back hurts when i drive in cars that have anything but those seats.
to summarize: these are awesome seats but only for most hardcore of us that can put up with very high bolsters and constant passengers' bitching, but they are glorious in high-speed turns.
..and they are definitely not mercedes-comfy
btw, $390 is a steal for those
