I hate American cars in the fact they are a b*tch to beef up or maintain. Japanese cars are easier to work with. In an American car, you have to remove the whole damn engine to replace a bolt. The position of everything is stupid. It is a little weird though having to use metric tools on the cars, but it is easier once you use them a lot, since everything is multiples of 10...never mind.
My favorite American company, though, is Chevy...i.e. Corvette, Chevelle SS...all that good stuff...
