Rules say you can't go over 70mph south of Montana, too. Gonna sell your Z06?
Here's your price (from Manheimgold):
Fair value for a base vert = $11,000
Adder for 454/390 = $5,000
My guess at an adjustment for condition from fair = ($5000)
My opinion of a fair selling price for your car (as described with no pics) would be around $10,000 - $11,000.
Manheim's definition of fair used for their pricing model:
FAIR - Essentially complete and functional. Missing no major parts. Suitable for restoration. Paint, chrome and bodywork showing age. Minor body or chassis rust. Drives, but engine, brakes, transmission not perfect.
Sorry if I offend with the price...I'm not in the marketfor a vert

, just trying to see someone here fulfill your dream of rebuild and get it for a fair shake.
