What to price a 1970 Super Bird at my friend is getting in a multi car trade

Ok, here is more info.....Galen Govier has inspected it so you could always buy a report from him.....440 4 rrl, numbers matching except the transmission housing was replaced on a trns rebuild (ahhhhhhh what an idiot)......3 year old motor rebuild documented and 12 year old paint door replaced but have the original still about 900 made....he is sending me pictures today
your friend might get burned on the deal if infact he is giving 80k, 10k paint job 12 years ago on a superbird sounds like a cheep quickie job, if its an auto on the colum that will hurt the value also. Someone who is going to be looking for a superbird will know where to pick it apart.
