Americar, Brazil makes GLASS cars, NOT alloy. At least there is no mention of any alloy car in the english language version of the web site. I don't speak "Portugese" but in THAT language on their web site is a picture of an alloy car. My guess is they made ONE, and if your Daddy War Bucks they might make another one just for you!
EDIT: By golly they DO make alloy cars!
