Agreed. I sort of thought someone with a replica might also possibly come along and ask to buy it, in that case, I'd have to decide. And, to your point, I could see someone with a replica Cobra wanting to buy it since it could be a good deal for someone, and at that point the only other motivation for me to actually sell it at that point, would be if I was looking to do something different with a powerplant, but I'm not sure what that would be.
It's always good to talk the brain through these things.
Also, on a related note, if I sold it, I've been pondering either a new Pond or Aluminum Shelby 427, just for grins, and that might just motivate me enough to sell it regardless.
I guess if the right buyer came along, I would sell it. And if not, just keep it and find another project. I guess maybe I just like tinkering with my Cobra, whether it needs anything or not - that's the (my) problem.
