If you do the math, very few cars are "worth" restoring from average quality, if you consider it from a financial standpoint. You have to do it for the cars, or you have to be a shop, charging the customer for every nickel's worth of time.
I also do most of the work myself. I don't set windshields, weld, shoot paint, or do the machine shop operations. But I can do the rest, and so I know exactly what is done and how it's done.
What pains me is to see people spend so much money on eBay for a car that it's not likely they are ever going to get to driving condition, much less restored. A lot of those cars are just too far gone, needing too much. They'll be upside-down on value from the moment they buy it, then pay for delivery or pickup, and start throwing money at it. It gets old real soon. I've had enough old cars to be able to tell the difference. I'd rather err on the side of caution, and I won't buy a car I'm not positive won't fill its niche affordably.
