In my area I think I would put that up for 9000 and be prepared to be talked down to 8000, straight cash.
The car has not had an easy life, has been heavily modified, and is high mileage. That's a tough sell. It would also be tougher for me, because even with my lightly modified car I would not sell it to a teen ager. I waited for the right buyer, in my case a father / son team, before I sold it. Turned down 3 people, I let 6 test drive it, car sold within 5 weeks of it being in the want-ads.
Vert only adds value if you're selling it during top-down season.
