Totally love my C4S - but I've never driven a TT...
I never feel that I have any lack of power, but more is always nicer.

 

what he said...I test drove a 2008 997TT 6sp and wasn't blown away to make me spend another 40k. My brother also a Porsche nut says it's sneaky stinky fast. Maybe that's why I like a high strung motor. I feel like I'm flying.

That being said if I could get one for a good price I wouldn't mind one.

 

the c4s sounds like a gem if you are indeed looking for a c4s, but the fact that you are comparing that with a 39k miles TT tells me afterall you want a TT
