P-guys, i am starting to have second thoughts. I have on order a 997 4s (see spec below). I currently own a 996 4s (which Ive enjoyed a lot). I am wondering whether to take the 997 4s (and sell the 996 4s) OR hold on to my 996 4s and later upgrade to a turbo in a 12-18 months time. What do you guys think?
