you don't understand. sure myself, like you and many others would like to see more performance oriented upgrading and not just adding 13 tv's and a dishwasher into a car, but the general population from ages like 10-18 like cars that "bling" and have cool rims and stuff. it's all about the money mayn, and if MTV just did a show where they made cars actually perform well, not as many kids would watch.
i tottaly understand what you're saying, but you have to think about what the "normal" population is interested in, and that's 32 inch rims on a buick or something.
