Auto here. Traded in my Audi TT Quattro for my Crossfire. The Audi was a manual and I was getting tired of it, especially here in Southern California traffic.
I find myself driving the Crossfire as if it were a manual. I prefer to slap my way around town and down the coast on the weekends, its just too much fun!
But, if you are really a die hard race fan, the manual is the way to go. You can do more tricks with those pedals (clutch, brake, accelerator) than you can with an automatic (brake, accelerator).
A little OT, did you know you can hold the shifter to the left for 2 seconds and it will automatically downshift to 1st?
