Real quick comment about PEHs remark.
$50-$60/hr of course in NOT what the technician is paid.
It SOUNDS obscene unless you try to work up a business plan where YOU have to pay off the loan on the building, make the electric and gas payments, pay the insurance carrier! At that point you figure out what you have to charge to keep the doors open and keep your family fed and happy, and it dawns on you; $50-60/hr isn't quite enough for you to live the American Dream.
I wonder what hourly rates MB Autowerks will have to charge to make it a thriving enterprise?
Sorry for being off-topic and I'll get off the box.
