Man Scott you hit the nail on the head with the first blow!
I quit watching ANY of these shows... they're either a bunch of stupid ass drama... or they're infomercials.
The only way to get advertising dollars is to do the infomercials.... and NOBODY wants to watch the idiots do stupid stuff on the old Boyd Coddington show. That was an embarrassment to hot rodding.
I think the problem is - building a car is too long - drawn out - and there's too much down time to make a TV show. The crews it takes to film and edit etc would be twiddling their thumbs far too many days to make doing these shows worthy of the investment.
When you calculate the amount of man hours in the super fast 7 day builds Foose was doing - it was like 2000 hours of labor.... and frankly the builds looked it. A giant bunch of poo.... and uninteresting TV. I'd have rather watched a guy get his car done in normal time and had the car be worthy of the effort.
