Really tough call..
It has the potential to be a nice car when done. It is not a common model, and it is one you want.
The main drawback is that either you are going to pay big $$ to have someone do it correctly, or you are going to have to learn how to do it yourself. Most of the parts you need to replace can easily be found on any A-body, so getting metal would not be hard. It is just that in reality it will easily be a few years before you probably get the body into a shape that you are satisfied with. Can you see yourself devoting the time and money? If you are looking to drive it within the next two/three years, I cant see it based on what you have said you have for money/experience. It would be a long term learning experience.
