Why only 3 stars, I'm comparing to my old dealer, Patrick BMW in IL which is a solid 5 star. I've owned 8 bmw's over the last 15 years and have been to 4 different dealers for service. Schomp service would rank 4th out of my very short list. The schomp process: call to make an appt, provide the list of things to addr, pull into service, stand by your car, review your list with the service tech. Folks relying on memory to address the items? I've had 3 appts and 2 of the 3 appts, some items were not addressed....oh we can schedule another appt to address the missed items. The patrick process, make an appt, then my service guy who I always worked with, would call or email to confirm why i'm coming in. When I brought my car into patrick, my tech would meet me, go to his desk, very civilized and we review my plan and he double checks everything on his pc. Nothing missed, they always addressed every item. I was just use to a very personalized experience, the schomp process just doesnt measure up.
