How much is a Chevy 65 truck worth?

it depends on how well its been maintained or even if its running or not if it runs good and does not need a lot of work then it probably worth a little more than one that needs a complete restoration right?

Example, 1965 Chevy C10, short bed step side, 6 cylinder engine, standard 3 speed transmission, could bring $10K in good condition. A C20, long bed fleetside, 4+4 could bring $9K in good condition.

It's all about condition and accessories.
