sorry but you're having a giraffe saying a 200bhp RST is a match for a E46 M3.
No RST is a match for an E46 M3, admittedly a 300bhp RST will probably match it in a straight line but overall the E46 is an awesome car, END OF STORY!!!
Editted to add all RST'S drive like the fwd tin cans they are and are basically shite, no matter how much power they have!!
