Rmember that at the Tokyo Game Show, the trailer said that over 80 manufacturers would be covered. And we do know this about Gran Turismo 4... in the case of American cars, we'll most likely get Buick because of that SEMA car who won the event last year or two. And I'd rather see some Trans-Am racing cars. They're more American than anything else. My only gripe about Trans-Am is that the machines look too much like "stock" cars and not so much of great GT2 or GT1 racers. Of course nowadays, the class would be known as GTS. Based on what I've seen online, I'm probably going to skip Cadillac altogether. All this company will likely feature will be the Cadillac Cien Concept Car (aliteration for you. Or is it?) and that CTS-V. If GT4 had the Cadillac Northstar LMP which landed on the podium in a few sportscar races (hey, some is better than none, okay?), I'd love to go to the Cadillac dealer in GT4. I even have a Northstar LMP with my die-cast car collection, give or take the rear wing I broke off of it by accident. The big three in America will no doubt be in the house for sure.
If I had to predict what machines would still make nice additions to the American car makes in GT4, I'll start with Chevrolet. And by the way, I'm not very educated with classic hot rods, so don't bash me if I left something key out. I wouldn't mind the Beretta, Cavalier, or any Impala before the one with the Skyline-like talilights. So a 1995 Impala widebody is mad sick as is a classic 1963 Impala. An El Camino wouldn't hurt. For Ford, I'd definitely want to put in the SVT Focus and even the Focus RS. Past Thunderbirds and Fairlanes would be nice as well. For DaimlerChrysler, the classic Plymouths would be nice. That Hemi Dart car is a nice way to take down opposition. The Dodge Omni GLHS is a good choice as well. Chrysler's LMP with Team Oreca (perhaps the best Viper GTS-R racers in the world) is not bad either.
Well, I'm either out of ideas or don't want to post more than I normally do. But, there you have it.
