For younger crowds, the stereotype is of an import crowd interested in speed and showing off flashy accessories that is much younger than a domestic car crowd who may be more about actual power and are out there because they want to meet up and talk about cars. Older people with imports will most likely have well maintained cars without the F&F look.

It takes money to actually go fast than to just sound fast. Need to attract the more mature crowd with good jobs and can afford an entry fee, pay for dinner at the restaraunt, and have something to lose with a reckless driving charge. As harsh as it sounds, the kids that live at home and are just out doing crop dusting fly-bys with their biplane wings need to be weeded out to get/maintain the actual car enthusiasts.
