Maybe the SLK guys...but the other MB lines (W211, R230, W203, etc) have extensively modified their engines and run them a good bit. There is a SL65 with about 1000ft/lb of torque on it, one or two E55 in the 10s off the bottle, multiple E55s in the 10s on the bottle. And the 600/65 guys are going crazy. There are some quite fast 600/65 guys. The Eurocharged SL65 is set to break the R230 record on 12/5... They've got the bug as bad as we do...haha.
