Opinions/thoughts on 1980 Corvette

[RJS]

I'm trying to help a neighbor put a value on his Corvette.

I've never seen it and it's in another town, all I know is what he told me last night.

His Family home will be going through an estate sale and his old Vette is sitting there in the garage for about 25 years, it was a running driving car when parked.

1980 White/Blue interior Automatic he thinks base engine (L48)
I assume A/C and all the standard stuff, only thing he said was he had changed the wheels years back to unknown???? I believe he said 68,000 miles.

I know this is nothing to really go on but what $ can he put on it as a non running car that we all know will need all the fluids/ maybe lines etc... replaced to get it going again.
I'm going to see if he can atleast get me some pictures from then and now but don't have either at this point.

Thanks in Advance
Ron
