In my opinion it's no more American than the Fords which run in BTCC or WRC. It was developed entirely by Swiss team Matech. Just like I consider the Toyota LMP1 to be German, not Japanese.
Having said that, I don't agree that Americans make inferior race cars (just look at the success Corvette has had in GT1 and GT2).
Oh I understand, I was mostly responding to this:
Doesn't everyone think American racers
(the cars) are inferior sadly?
My point being that Matech isn't Ford, yet they developed the Ford GT and made a competitive car anyways. Which to me speaks highly of the strength of American machinery as the basis for a racing car (though some still might argue how 'American' the Ford GT actually is, Clarkson-style).
The only truly American GT3 machines are the Vipers and now the Cadillac currently. With only the FR500 GT3 also counting an American developed heritage. Both Vipers (The Comp Coupe and GT3-R) have held their own, we have yet to see what the Cadillac can do, and you already know how I feel about Pony GT3's.
Head up to GTE and you'll find race and Championship winning Vipers (RIP) and Corvette's beating factory BMW's, Porsche's and Aston Martin's. Even the Panoz Esperente GTLM was a competent car back in the day.
Scroll back to the second iteration of GT1 and you'll find Corvette's and Saleen's doing work (in addition to the Matech GT GT1's).
The First iteration of GT1 was silly money-blowing nonsense, but even then the front-engined Panoz's showed well against Porsche's and Mercedes' that had loads more money being thrown at them. Meanwhile the original Viper GTS-R was cleaning up against a swarm of Porsche's in that era's GT2 class in nearly every event it entered.
The last time the Big Three spent good money to win Le Mans outright, they did (And no, I don't think GM spent 'good money' on their Cadillac LMP program, before anyone says anything.). Several times in a row in fact. During that same era, a crazy Texan was slaying Ferrari's with Anglo-American frankencars that had snakes on the hood. If you have a problem calling the basic Cobra an American car, then what about the Peter Brock-designed Daytona version? That car made the now-fabled 250 GTO look silly. I also believe the all-american Chaparral's deserve credit for a lot of racing innovations.
Anyways, I'm sorry for continuing a very unrelated but spirited conversation.
