Hi Michael...I was in a thread which beat the subject of the Sport package to death and still didn't resolve it. I was told that it had the AMG 32 suspension kit, along with the body plastic and AMG chrome wheels larger in the back than in the front. Not wanting to argue, I did point out that critical suspension components for a 170 have two listings, one for a standard SLK and one for the Sport package, which includes the AMGs. I don't like to argue with experts, but really feel that parts numbers reveal everything. I think much of the confusion is that there were not many pre-facelift Sports Packaged cars, or at least as many as you see for the 2001-2004s.
They are all nice cars and if they were alike, well, that would be boring, wouldn't it?
