Personally speaking, I'm not much of an innovator on mods. I'm more of a "purist" and try to keep all mods from being "permanent" so that if I choose, I can go back all stock. For example, I just ordered a catback. But I'm keeping the stock exhaust just in case. Nothing on the car so far has been done that can't be undone.
That said, I get something out of Camaro forums and the people. Very creative ideas and folks with huge sacks (or ovaries as the case may be) to go and use their car as a starting point for making their dream car. And hopefully, that gives me ideas as well. I've spent a few bucks I probably never would have had I not seen others do first. I don't want an exact copy of someone's cars, but the ideas don't hurt when you can actually see the results.
