I am trying to sell my 1985 Corvette, how much should I list it for?

I have a 1985 Corvettee in pretty good condition. I have researched online but there is a
huge range in the pricing. I have seen anything from about $4,000 to over $12,000. My
car is in average condition. Nothing major is wrong with it, just some cosmetic stuff like
needing new carpet and some body work and a paint job. The leather is perfect and the
tires are like new. The instrument panel needs to be refinished because it is faded and
it has an after market steering wheel and stereo. It still has the factory sound system
with he exception of the actual stereo. The wheels are Corvette wheels but not the
ones that came on this year model. Also, it is missing the headliner for the Targa top.
It has a new A/C compressor, new window regulators, new battery and tinted windows.
The car runs great and I am getting a lot of people interested, but I have been unable to
get anyone to actually come look at it. Please help because I need to sell it soon.
Thanks!
