I did some looking at specs between the 3s and TC. The 3s was .4 sec faster in 0-60, but the TC was slightly quicker in the 1\4. TC was a couple hundred heavier. I have a p5 and my friend has a tc. the TC is a nice car, he let me drive it and yes it DOES feel a bit sluggish on RPMS but the car has no problem chirping through 4th gear, I can barely get my p5 to chirp second... They dyno'd the TC in the low 140's stock, and I dont know what the 3s dyno's at. If they m3 handles like my p5, that would be the decision maker for me, stock my car handles beautifully...
