Part it out, and use the money to get a car finished to closer to what you want.
With project cars, it just seems to drag on endlessly
Yeah, the buy-in is higher, but the pay-back is much more rewarding.
I have to say that I tend to agree with AJ on this one. I guess it comes down to how much sentimental value you have in this car. If it means a lot to you for some reason, I agree with the others on here about keeping it running as much as you can. Doing a full tear down can get too big and you can get stuck like I did. I decided I wanted to do a full rebuild of my Charger. As we dug into it, the size of the project just got bigger and bigger. Had I not had it since I was a kid, I wouldn't have continued and would have gotten rid of it long ago. That's why I bought my Barracuda. It was mostly done, and just needed little things here and there while driving it and enjoying it.
The other problem with big projects is if you can't do it all yourself. I'm not a body man, so I am relying on others to do the body and I have already had two different shops back out on me for different reasons, leaving me with a car all tore apart and having to find someone to take on the project in the middle. Fortunately for me, I have a brother-in-law that runs a rod & custom shop so that is where it is now.
So,... if it were me,.... No sentimental value = sell it and find something closer to done that you can drive and enjoy while finishing it. Sentimental value = Get it sealed (floors & roof) and on the road and do what you can as money and time permits.
Pic of my Charger at the point the first body guy bailed on me. He was working on it out of his home shop. Got caught cheating on wife and forced to move out!!:BangHead:
