the locks and other vacuum related features of my car suddenly stopped working, so i went to Jeff. he was afraid it was the vacuum pump, which would have been really expensive. instead it was just a wire that came loose. i'm sure there are folks out there who would replaced the pump, out of greed or incompetence, but Jeff and his guys just fixed the wire, and for an hour and a half of labor, i was on my way. you can't beat Jeff!
