Hey all. Sold my 996 Turbo last year, looking at a '91 Turbo as a replacement. Where is a good place to put a value on it? Can anyone here help out?

What I know about it so far is, 89xxx miles, blue, appears to be unmodified. It does list prior paint, but no idea why. Carfax is clean back to '94, no data prior to then. It's only been driven about 25k since 2000. Appears to have been a CA/AZ car all it's life. Currently in FL.
