Chevrolet Biscayne Forum : “what is the average purchase price of the 1959 chevrolet biscayne in good condit...”

Somewhat depends on the mileage and options (also is it a coupe or sedan?) but I would say the average price for a sedan in good condition is about $6000. They can go for as much as $9000 if they are in excellent condition.

Here is where I got my info.
