Gary, I struggle with the same issue. I have a 1994TT with the factory paint and a few mods. It has 53,XXX miles. Yes I could get 15K for it but what can I replace with that amount? A Ducatli Panigaleis 30K plus another 15K dress it up. A comparable performing car exceeds 100K. So.., I have concluded WTF for, should I sell the Z? Or my Buell S1, or my 19 + 1 Springfield Armory XD or any of my old shxt? The only reason would be if you just don't want to play with it anymore.
