72 340 4spd TX9 and 73 340 4spd Triple black Cudas. What are they worth?

10k-ish sounds about right to me. I got my 73 Cuda for about that. It was in rough shape when you looked closely and turned out to be even rougher because of hidden accident repair that was poorly done. Cost me several thousand in frame/unibody repairs that I wasn’t planning on. Go in with eyes open. Mine was pretty decent on the interior. If I was to do it again I would have passed and got a better condition car for a bit more money to start with. I wanted to drive it while I did most of the work but it’s been torn apart for four years now.
