nice switch and I agree 100% with it. The GTR is a very fast, capable track car. But who cares right? No one is racing cars on the street. You can't even race people on a track.
Life is short, go for the car with the fun factor, speed isn't everything. If it was, everyone would have a GTR.
I would have picked the 991s 100 out of 100 times over the GTR.
