new ride, 68 barracuda formula 1 ? Help Decode !!!

Ok, I guess the question is, What's a rebodied 68 form. S , with $5000. of body work done to it. worth ? Compared to an original with $20.000 worth of body work done to it ? Am I going to come out ahead ? I think I will come out about the same in Value after the fact of my cost . My problem is I don't have the 15 to 20 thou. to spend, but I can come up with the 5 to 10 thou.
