How much would you pay or whats it worth

Im looking at a 69 GTS 340 four speed car. Its factory b5 blue with blue interior and bucket seats. It is a 340 four speed car as I said . I dont have pic to show you but he said the body is pretty decent but needs one rocker fixed and some fender work. Its in primer and needs finished out. The under side of car is very solid needs nothing. The engine is not the original but the trans and rear are. It came factory with 3.91. Interior is good no rips , but no carpet. The drivetrain is good to go he said and engine is good with X heads and weiand intake with 750 holley. Also he has the stock manifolds to go with car. He has orignal wheels also. Seems the car needs minimal body work and finished inside. There are not many 69 gts four speed cars. The registry has only 24 listed granted Im sure there more. Thanks guys
