My guy who is famous in the Shelby/Mustang/Lightweight Fords told me that doing to car over so you want to enjoy it but not thinking too much about value will make you happy in the long run, He was RIGHT. Also, that has to work for you.
My dilemma was I had 4 deadbeats working, or looking at my car for a total of 10 years, I was so deep into it that cutting it loose was really not an option, also I wanted to prove friends wrong and get the car finished. I ended up taking to who I should have taken it to first, and it is now a beautiful car! I probably (with the market in decline factored in) have about 40K more that it was worth. If I took it to my guy right off the car I would probably be into it for a profit of 10K. But, I had the money to put into it and it makes me very happy every time I drive it.
That being said, I have a friend who might be interested in the car if you don't want it or if you want a fee of some sort for it. Just saying....
