In my personal opinion, the 3.2 AMG supercharged V6 engines vary in power. I read several SLK 32/ C 32 tests and the differences were substantial. My wife's SLK 32 AMG is almost "spectacular": I outran my neighbours 2000 996 C2 with Techart engine kit (25+ HP), a friend's GT3 (stock) can't pass me up to 220 kph and a 996 Turbo with Tiptronic has a completely identical head-to-head acceleration up to around 180-200 kph. Unbelievable. But as far as I heard, there are some SLK 32/C 32 out there (apparently especially early model years) who have huge differences in power output. I'm happy my wife got a "good" one. And for all people out there who are looking for a nice and powerful everyday car: the SLK 32 is great.
