Hub long ago drove for free. He gets beaters from tow yards or auctions and used them to commute as he fixed them up and then flipped them for a couple grand. The problem is you need the auto education. It's harder and harder to learn, you have to have theory. Go to school for some night classes on cars. Get your hands dirty on other cars using other's tools, make your mistakes on them.
Hub has more than 60K in tools and that was in the early nineties dollars post USAF retirement
Could be a larger chunk of change now.
