I had the same thing happen to me. I dropped my car off for the 1200 mile service and they gave me a rental because they were behind that day. They called me towards the end of the day and said it was ready. The tech said pick it up in the morning since I was an hour away and they will have it waiting for me. I thought better of it and went there with them still thinking I was coming in the morning. When I got to the dealership, I didn't see my car. Five minutes later I see the sales manager pull into the dealership with a sheepish look on his face while I'm standing there with my arms folded.
