If you get to know the guy, it might not rub you the wrong way. Had a Lexus tech that owned a car similar to mine, and he turned out to be a great tech and resource for information after I got to know him. Trusted him implicitly when he worked on my car, I even encouraged him to lay into it on one of his test drives just so I could hear my own car from the "outside."
In addition to this, find out how many Stinger trained techs there are. He may be the only one and anything beyond an oil change will require him to do it. Get to know and trust him.
