I see so many guys go and spend 30K on a Wyotech diploma only to just have a shot gun blast of the basics. If you know you what to learn about how to build or work on cars, I think your money ahead to just dumping 30k into a desirable project. Just work on it until it's perfect. At the end you shoudl be able to get some kind of return on investment.
It's more important to care about the results then to actually have skill. You can learn skill, talent only speeds up the process. If you don't like it cut it off and off and do it again.
What is the worst thing that can happen, you have to re-quarter panel the car. Heck even some proshops can't do what you workin on. So the car goes to another shop to be re-quartered. I'm sure you have seen that a time or 2.
