I've spent a huge portion of my life looking at Porsche 911's on the i-web and trying to decide which to buy. At one point or another, I've been convinced that I should own everything from an original 911 to my current dream, a 997 GT3 RS. I'm not sure about is the new 991. The great news is that this has been going on for years and, so far, hasn't cost me a penny. What would/have you choose or chosen?
