You will cry if you sell the GTP.
I have owned 5 birds of various years. They are good for something. Ornaments. The 79s were great lawn ornaments and money guzzlers. The other one, well, let's just say it was easy enough to disassemble and leave it at that.
I get more comments and compliments on my 9 year old GTP than I ever got with any of the birds. On a side note, the camaraderie in the local GP community is much greater than the trans am. I mean, sure I complain when something little breaks on her, but it's always something fixable.
My GP will more than likely be my coffin. I have yet to find anything I like better. Well except maybe Mike Vaughan's new caddy. That looks like loads of fun to drive. However, it is against my religion to spend the same amount of money on my mortgage and car payment, so that's a NO.
