The fact that you are considering it tells me that you are not totally in love with it as much as you thought you would be. Is it this is exact car that you are not in love with, or is it the 40 in general. I always wanted a 58 chevy, once I got it, it was a delray, the interior was so dang blah, that I sold it really quick. If this particular car is not the right 40 then sell it. Even if you pay 20 for one that is further along and in a better state for what you want, you will only be into it for 10K. Just a thought. The only regret you would have is if you sold it for what you paid for it, if you sell it for what its worth, you can pay fair price for another, and all being said you will be in it "right"
