What do you want to know about the SLK? I've got 15 or 20 of them floating around the store at any giving time.

The XF is a 170 chassis SLK ('98 to '04). The differences are in the body, trim and vario roof vs soft top on the roadsters. Naturally, there were no fixed roof SLKs.
The drivetrain is essentially the same. We hooked my SRT up to the MB system and got into everything except the shifter and ESP.
