There are some group buys in which a certain number of people need to be paid before production can even start. These group buys often run over 6 months, some over a year before production starts. If you aren't willing to invest the time in a group buy for a quality product, you have no business participating.
Patience is a virtue, and good things are worth waiting for. Where else are you going to get a header like this for that price? That's right, you're not.
Charles is a stand up guy, he's not going to run off with your money. He's given periodic updates explaining delays. If you need a header to finish your build in two weeks, this group buy is not for you. Buy a f*cking SSAC.
Charles is a very talented guy, and he's come up with a lot of cool stuff for our cars over the years. All this negativity is going to make him really think twice about future opportunities to develop new stuff for this community. STFU.
As for production issues, I'm sure doing a large number of custom pieces as quickly as possible, mistakes can happen. Again, Charles is a stand up guy, and I'm sure he'll stand behind his product and make it right.
