I bought the GTA and Berlinetta on eBay this week, and I found the Iroc-Z on an F-body forum. I also snagged a 1/8 Iroc-Z from eBay this week that should be here any day now. The Berlinetta, as far as I can tell, is minus the instruction booklet, decals and two wheels/tires...possibly more, but I don't have the instruction booklet to figure it out. The GTA and Iroc-Z are open but complete. The 1/8 Iroc-Z has been minimally started, but he said he disassembled what he had done and put the parts in bags, and he said it's complete as well. I got all 4 of these kits for about $260 shipped, so not bad at all!
