1973 what's it worth

[Sharky]

Ok I am new to the square bodies. I have always messed with 67-72 but I have found a 73 custom 10 orange in color six cylinder three speed. This truck was bought new for the man I am buying from his wife has been under cover when she was not driving it . Original paint that I think will buff out to look as good as it was new. No ps or ac. Is it worth $2500 was going to pay him for it tomorrow but wanted some input on it first. I will get pictures tomorrow was afraid the man might get to thinking something if I took them while I was looking at it today.
