My grandmother passed away a couple years back and I got her 1971
Cutlass Supreme. (Originally purchased by my grandfather in October of
1970)   I've had the thing sitting in my garage thinking I'd like to
restore it or build it into a fake 4-4-2, but the realities of life
are getting in the way of taking on a project of that magnitude so I'm
seriously considering selling it.  

The problem I'm running in to is finding the car's value.  The Kelly
Blue Book site doesn't offer values on any cars earlier than 1984 and
e-mails to various Olds clubs here in CA have so far gone unanswered.

Anyone know of a site or organization where I can find this vehicle's
value?  

Thanks!
