1981 Canadian Z28 asking price

Hello all,
I have been charged with selling a neighbours 1981 Z28 t-top and was hoping that I could get some input as to a fair asking price.
It has the (rare? canadian?) combination of the 350 cid V8 and the 4-speed auto tranny with just under 64,000km on it. The body is rust free. It has not been driven in some time, probably over ten years during which it has been kept in a heated garage.
I appreciate any input/thoughts.
cheers.

hey,
 
what color is she?
im looking for a black one with t-tops
 
have an uncle in bc who could look at her for me.
 
thanks

where abouts are you? i know one of our customers at work has a 73 camaro numbers matching car that we maintain for him and i think it is appraised at somewhere between $30,000 & $40,000
