Knowing from what wikipedia and other sites that show specs of the car you wont think its a huge difference but driving experience csl all the way driving it you really appreciate the car. Power wise, the way it just eats the road. Suspension is like nothing else ive ever driven. Handeling is insane especially in track mode perfect handeling with some room for fun the occasional boardslide hehe.. This is now compared to standard e46 m3. So after this i chipped and put on a k&n induction on the normal m3 so ive got a bit more power on the normal one csl on paper 261/265... M3 normal has the 252 now 27* still because of the driving experience you get for the csl the normal m3 still cant compete with the csl... My overall all conclussion is my csl is my favorite just a shame he is grounded this collectors item is kept clean under his blanket in the garage had an awesome opportunity to have one with less then 50000km on the clock now 45329.. Want to keep it under 50000 for as long as i can but the urge to drive the car sometimes is just too big haven driven the newer supercars saying driven not owned c63 amg new m5 for me there is not a car to beat my e46's beautiful and more then enough power to have fun with. Yea well hope that says a little bit
