What the hell is going on with shops?

I trust in the free market to set prices. Many people say "pay someone to do it and you concentrate on what you do best". That ignores all the "transaction fees" like taxes on both ends (my pay and their income), different agendas - I want cheap, they want to ream me, and trust issues, plus the costs of frustration. Turns out easier for me to just do it myself, whether mowing the lawn or fixing the roof. I need exercise anyway.

Too many people claim to be "professionals" when there is little skill in their profession and no degree required. I rebuilt 2 Mopar transmissions without ever having attempted one before. It was quite easy, I just followed the manual. Easier than hauling it to a shop and back and waiting for them, plus fretting over the bill.
