I say go easy on Swamp here. He does deserve credit for taking the time--together with other members--to maintain the list. I don't think people have been intentionally leaving cars out although the list is certainly made up of cars that people on this forum "see" as the competition. I don't recall seeing published performance data until recently for the GTR, so that's probably why it was not on there. I agree that it should be added, which I think happened already...
