When I read the first post I was trying to think of something to say that would convince you to keep it.... when I jumped to the end it was clear I did not need to say anything! I too have spent way to much on "less desirable" cars and that it what I want to do. If you go into this thinking "will I ever get out what I put into it" then you should sell it before starting! You need to go into in with both feet and say "I am going to make this thing better than new" so when you go out to the garage and take it for a drive you can say to yourself, "yes I spent way more than it is worth but I a proud I saved a 318 or /6 car". You will find there are a lot of people out there that will congratulate you for it. I was offered WAY more than what my Coronet 500 was worth, but about what I have in it, at one show but I turned it down because I have become too attached to it... My daughter and I are now doing a Duster for her. I will have 2x more in it than it is worth but it will be better than new and we don't care. You are doing this right and I will guarantee you will not have second thoughts once you are done! Great job.
