Heh. The old ‘machining’ the rotors trick. Gotta be a good moneymaker for lots of repair shops. Most people aren’t going to second guess a mechanic, and brakes, well, they are important! The fact is, turning rotors isn’t strictly speaking even necessary nor desirable.
The trick is to understand what exactly is broken on your car or truck. Whether male or female, if you show up and say “My car won’t start” then they have just hit the figurative lottery. They can throw parts at it all day and charge you the max rate for labor.
On the other hand, if you are able to track down the specific problem definitively or nearly so, you can limit the damage they do. Just be thankful there isn’t a federally subsidized Carecare program similar to our health care system. Can you say $1000 oil changes boys and girls? heh.
