One it's a 2+2 so it's heavier and it's a 1990 so it's the oldest Z32. And for $11 you can get a TT...But your seem to have a lot into your car and by the way you describe it it seems to be mint. As everyone else said wait for the right buyer. You may get lucky. I know how you feel, I dumper atleast $10,000 into my Z31T which was my show car and I only got $5000 for it. Best of luck.
