I finally got tired of the Crossfire seats. They are typical Mercedes design and hard as a rock. If that was fixed and they a little bit bigger I would like the car much more. Today I traded my SSB 6 speed (1900 miles) off for a new Corvette. I liked the seats better and the room is more also. For your information if anyone else is thinking about your investment the 6 speeds are bringing $28000 wholesale. If they start bringing out rebates it will go down. It is bad enough I bought mine under retail sticker but would have been really bad if I had paid over sticker for it. I have learned my lesson on Mercedes design.
