I've seen TT's with less mileage and original parts go for less than that--z's also seem to be a lot cheaper in the larger cities--I looked all through austin and dallas classifieds before going to dallas to get mine--I think you would be lucky to get 10.5k for the car though I have not seen it and don't get me wrong I'm not putting down your car it's just that despite the money you have put into it many people are not going to see that as a good reason to purchase the car--I feel your pain as I am only 20 and maintenance sometimes makes me want to cry also--Good luck!
