I have only seen the show twice...
... but from what I've seen... there is definitely some hokey stuff they (the show) pull... they without a doubt plan the projects for the teams... so the solutions are somewhat ... "there"... already.
.. and I will say one other thing.
With us 3 Michiganders... we really are actually still missing one thing for sure... non of us are really hard core mechanics... I am talking about a guy who has repaired cars or trucks (for a living) for 20 plus years.
I consider myself a 'good' mechanic... but there are things people learn from doing it for a living that you can't just by 'fiddling'.
On the other hand... some of those 'professional mechanics' have next to no creativity.
Me?... I'm half mechanic.. half designer... half fabricator... (and I still can't count)
Oh yeah... something else... My last "real" job... I was foreman/general manager of a 15 man fabricating shop... so I am a summmmbitch too... : )
