427 Biscayne

[coilover]

I could really use some help on getting a value on a 1969 Biscayne. If this is the wrong site maybe someone could steer me to a correct one. The car is a 427, 425HP,with a rock crusher 4sp, radio and heater delete. My shop was restoring a 54 Olds 98 Starfire convertible for this man (and friend) when he had a fatal heart attack. Now his family has asked me to get approximate values for his large car collection. I don't know the muscle car market and don't want them to ask a rediculous price or to give it away so that's why I'm seeking help. It shows 8K miles but alot of that was probably put on a quarter mile at a time. Very clean but paint is getting thin and has some crazing. Any help will be greatly appreciated. Thank you; Evan
