I've been trying to figure out how the 997S and my 2004 M3 compare by studying their engine performance output charts (HP and torque vs. RPM).

Since my 15 minute "test" drive of the 997S wasn't the greatest, I'm still wondering how the two compare.

Has anyone here heard reliable reports of, or spent significant time side-by-side in a new M3 and 997S?

How would you compare the "thrill" factor of these cars? IOW, in everyday driving situations how do they compare?

Any _responsible_ advice or opinions would be appreciated.
