Rick,

There are so many things that determine any collector muscle car's value: overall originality, original drivetrain, original sheetmetal, original glass, original interior, performance options, dealership and factory documentation, original owner's documentation (such as vintage photos, racing trophies, time slips, etc.), ownership history, race history, delivering dealership, if restored - quality of restoration and use of original or nos (factory line correct pieces or over the counter?), color desirability, auto vs. manual, is it known and been displayed at prestigious events such as MCACN or a concours, has it been judged by a recognized/reputable group, and on and on...

It is tempting to use auction house prices but that is usually not a good idea - can be very misleading. The camera can make any car look good and you usually do not have the inside track to the above items I mentioned. If you really want to know the value of your car, get someone who knows these cars (w/ a good reputation) to look your car over. Guys like Stefano Bimbi of Nickey Chev and Marlin Spotts (Deuce Registry) are good places to start. These guys know these cars and the market.
