I do very little side work. Occasionally for relatives and sometimes a co-worker in need i'll try to help out. Not for anyone who would normally be considered a "paying customer", that is strictly verboten.
I don't understand the comment about "handing the car to a dealer" who then gives it to a $6/hr grease monkey to work on. I AM a dealer tech you know.
If you want me to work on the car you can certainly request that I do the work on your car. Presently we have a 4 day work week, rotating day off, you would have to check with Greg my service advisor to make sure I am scheduled to work on the day you have in mind. There are several people who request that I work on their car.
