Leather interiors are not well suited to a "group buy" because everyone wants something different. Group buys are great when everyone is buying the exact same thing. If you want suede inserts and I want perf leather inserts and we both choose different wrap colors and stitching and you have 4 captains chairs while I have a 40/20/40 front and 60/40 split second row, what we have is two guys buying leather interiors at about the same time.
The advantage to a group buy for the seller is that if he has to manufacturer something he can know before hand how much he's going to sell so he can give the buyers a lower price than he could if he didn't know and had to assume more risk with his inventory or manufacturing process. This in no way characterizes leather kits. Every Katzkin kit is a one off, unless you're going to buy 50 interiors that are all identical in every way.
I have seen two "group buys" of Katzkin interiors on other GM truck forums go very, very badly. Also, $1000 is about market price for three rows and no fancy options.
