This is a tough one. I've been wrestling with this very idea for some time now. For me, the problem I have is the big question, "Are my skills there yet, to do the dream car?". To answer that for myself. Nope not yet. I still need to learn the mind knumbing paint skills. So the kit sits, waiting. But I'm cool with that, for now. I'm working on it.
A man visiting New York stopped and asked a local street musician, "How do I get to Carnagie Hall?"
The musician lowered his horn and said, "Practice man, practice."
