First one that I found that suited my username and was too lazy to look for anything cooler. Now that I think about it, I might as well, no, nevermind. Still too lazy.

Reasons being for absence of knowledge on American cars is my prime interest in JDM, on the other hand are the exciting, powerful cars made by Lamborghini and Pagani, of which also take the spot. I've never come to like American cars, and as stated, lacking of knowlage and interest is the main reason.
