I actually disagree with most of your points. I am on my third kit, looking at a 4th. It has never taken more than 6 or 7 months to finish any of them and I can only work on them for a few hours on the weekends. I have also made money on all the cars that I have built. The build itself is therepy for some of us. I have not been that impressed with a factory car that is exactly like the next one, maybe just a different color. As for resale, in the cobra world, the Kirkham and ERA are at the top of the list and they both are assembly required. I don't think there are near as many unfinished kits as you think.
I am looking at the RCR kit and I can get a kick ass 550hp/600ft/tq with webers, your ZF and a great paint job for $25,000. The RCR is less than 50 grand to build a turnkey minus. The factory built cars are $20,000 more! For $75,000 I will have a car that will be as good if not better than any of the much more expensive options. The only variable is my time and ability. If you have time and ability and really enjoy the project, the economics are in your favor with a kit.
Just my $.02!
