There are many different types of enthusiasts... I don't think you even really have to own an import car or something similar to be an enthusiast. I would say knowledge is the basis but the more knowledge and the more experience the more of an enthusiast you are. If you have love for the import scene that is just the beginning.

As far as all of the fuckheads doing burnouts, thats just childish... We are lucky to have that place where we can meet and not get bothered by cops much at all. These kids are just messing all that up for those of us REAL enthusiasts who don't need to show off to get something out of a gathering...
