MS3 isnt bad.... its definately awesome in the engine dept. although I guess an extra 100hp and 110tq will do that...
having driven both, I just feel more connected with the MSP. It handles better, reacts quicker and has better feedback. Im not saying the MS3 is bad with handling, just not as good.
now comfort/convenience... stock for stock - definately the MS3... Im in love with those seats. If only I can find a way to stuff the frontseats into my MSP...
