The only real car show I think is Gearz with Stacey David. It's him and a few helpers and he builds everything in that shop by himself. I've met him a few times and the guy is real. Except for that terrible hair and laugh, he's ok.
I used to watch Sam and Dave years ago on 2 guys garage, now they have these 2 assclowns. All of the "powerblock' shows are ridiculous. Mega money thrwon at cars that underperform and underwhelm. Those guys have every imagineable tool and equipment at their disposal and still produce crap. GMG are a bunch of butchers that is fake- all of those sales are scripted and phony- except for the auctions where they lose their azz. Car Warriors with Jim Shine is another joke- half assed builds that are unsafe and ugly as sin- and totally scripted. Chop,Cut, rebuild - another too much money for brains show where rich Bentley owners throw out six figures to have someone else build them a car.
