Yep, the Mitchell Labor Guide is alive and well and in use at reputable service providers today, or still was when i was 'in the biz'
I still call them Stealerships, the parts are marked way up even from the inflated price the manufacturer charges the stealership, and the rate you pay for service, compared to the rate they pay the mechanics, is criminal, especially since many of them don't pay the mechanic 'on the flag' as they should
For those who aren't familiar with that term, being paid 'on the flag' means you get paid according to what the labor guide says the job takes, not how long you actually take doing it
This incentivised the tech to buy tools that make the job easier and quicker to do, AND to do the job right, since redoing a job you botched pays nothing
So for example, a 1998 Chevy Lumina shows 1 hour to R&R front brake pads, which means the consumer pays 100 for the labor
I was capable of doing the job in 10 minutes, so at $20 per 60 minutes, I would make like $3 and change, if I worked hourly, where I should have been paid $20 for the job according to Mitchell, and there you go, I get about 20% of what the customer paid, despite the fact that i supply the knowledge, the actual labor, and the vast majority of the tools, and if I'm hourly, I get paid 3%
customer and mechanic are both being screwed
