Graveyardcarz is restoring a 71 Demon 340

I totally get that, I'm sure it gets nicer the deeper the pockets. I've just heard stories from all levels of shops, no matter the quality they claim to produce. The guy with a Daytona going for OE gold sure isn't going to skimp on little details.

50-90k would build my fleet of 3 and give me a garage to boot.

For sure. I agree. A car has so many components. So many variables. There will be mistakes. Some just bigger than others.

That's with you doing the work. And maybe you don't want the same level/result as a full tilt resto. You just have to have skills, time, and resources.
