To understand the tuner market, you need to look no further than the fashion industry. Before you consider this statement ludicrous (or downright shameful), consider the parallels. In fashion, what is considered innovative and popular is usually determined by a small but influential buying contingent. Those who work in fashion must attend shows and watch consumers at the "street level" to get a handle of the marketplace. So, too, must successful tuner product retailers and distributors get a handle of what's popular by eyeing street-level activity, whether it's attending shows or going to the local weekend hot spot where drivers are comparing notes on their customized rides.
