I have been following this thread for quite a while and understand everyone has been trying to be helpful even if it seems "harsh" at times.
Deciding to build your own car involves a lot of emotion, dream, expectation and desire. I've been through it. It is exciting, fun, grueling, exhausting, satisfying and expensive. I expect to keep my build so I'm not concerned about resale value but that is something that should be considered also. A one-off build by an unknown builder using unknown design and with questionable construction will NOT bring in much resale value. BUT, if that builder has something that is a known manufactured product, well constructed and recognized in the marketplace, they stand to get a fair value if they do sell.
So, keeping that in mind, I would suggest (especially for a first time builder) to look to someone like Factory Five. They have KITS. FF can provide everything you need to actually get your build finished and offer support if you need it, directly from the factory. Their product is recognized and of very good quality. So if you DO sell, it would be of value on the market as a known product.
People here know me. I am NOT shilling for FF. I don't get anything for this recommendation. I'm just trying to put some real world sense in the decision process and try to help a new builder see another option.
You could also go with an engine-minus buy of something like a GT40. With that you would still have some work but you would be up and running very quickly.
So those are my "words of wisdom". I know I can't talk you out of your dream build AND I don't want to. Just think about what I said before you make your decision.
Whatever it is, people here will be glad to see and hear about your efforts.
Good luck.
