'73 Targa Project Car - Value???

[vouvray]

I have had a '73 Targa for going on 7 years now. I have re-built engine top end w/ new rings, and its ready for valve timing. Have nearly all the parts to complete car, but do not have time to finish it right now. I just found out that I am going to be out of state for the next couple of years, and hate to see that car sit and collect (more) dust. Any idea on the value of the car as it sits? I have new lens, rear deck lid (w/ tail), front RS spoiler, all body gaskets, hood, etc. I do not have carpet, and the top needs new skin.
