68 Impala Custom, survivor, current market prices?

[Tommy_Mathison]

My uncle just bought a 06 Vette convertible and would like to sell his 1968, 327, 2dr Impala Custom that he bought new in 67. I have no idea on current market prices for cars like this. I must tell you this car is a TRUE survivor. 40,000 miles, Zero rust, 95% original maroon paint in prefect condition. Original interior (perfect), fully numbers matching, original 327 and Powergilde. Chrome is all original and also mint. Has a new water pump, tires and battery. Always garaged. My question is what is something like this worth? $10,000? $20,000? $30,000? I really have no idea! Any input is greatly appreciated. Thanks!
