The other is finding THAT guy... that sees the car at the numbers being thrown out here. Trying to be fair and impartial I would say that car, as is, would be in the 11-12k range as a complete turn key car. Pros are all the mods and work done on your end. Cons are color and the fact that it's not a true TT, it's a highly modified and converted sports car which always brings up the reliability question. That's it in a nutshell. We all know that you have way more than that invested but that will never drive market value. You have to weigh that car against every other quality TTZ for sale and what they actually sold for, not what they asked. The guy with 15k to spend will be looking at your car but I wouldn't expect it. Just my opinion. You're deeply invested in the car so if you want to recoup as much of that as you can my suggestion would be to part it.
