What’s my 61 valiant worth?

I`ve got one ive got 3500 in it. You cant find em. its millennial theft proof. 3 speed on the floor 2 door. You cant find em and they are lighter than the 64 on up so it is a perfect race car. So ugly its beautiful. Mile is listed for sale but if it doesn't sell will keep it and drive it someday. They are unique.
