Based on what I paid for my '57 3600 I'd say between 500 and 1500 depending on condition. You are going to spend ALOT of money just getting it road worthy, never mind restoring it as you will probably want to do. See if you can drive it, if it runs, has a good non slipping cluthc, has brakes, look for leaks at the wheels (brakes) pop the hood and listen to the motor, look at the rust, check the hooker. If it's a beater then the lower end of the range. If it's in driveable shape then the upper end of the range. Have a number in mind and make your offer with confidence as you will probably be more knowledgeable than they are. Good luck. Send us a photo!!!!!
