The problem is not enough return on their investment. A lot of interest is expressed, but when it comes time to put up, no one wants to do it. To be honest, the reason most people opt for the Aveo over say a honda is because of PRICE. Well if the people buying Aveos are worried about price, they are not inclined to purchase expensive aftermarket parts. That along with the fact that there are so few Aveos, the market just isn't there.
