I'll take the other view..
The S2 is definitely more dependable particularly when driven hard (i.e. track) and while the top end speed of the 951 might be a couple of MPH's faster you'll be hard pressed to capatalize on it unless you're into drag racing which these cars aren't meant to do IMHO
Yes, you have to be religious about maintenance but you should not own a P car unless you're preparred to be (or have deep pockets...)
