Thanks so much for allowing me to service your vehicle.
Your experience and Complete Satisfaction are two of the most important things to me personally, and to Kansas Dealership.
As we spoke when you were at the dealership, General Motors may invite you to take a survey about how I did. If you want GM to know what a great job we do here at Kansas Dealership, please submit your Completely Satisfied survey to them. It helps them to realize how important local service really is to drivers like you.
In case you are unable to tell them you are Completely Satisfied with any part of the experience you had with me, will you please call me first? If anything is NOT right for you I will definitely fix it.
Please call me on my direct line at 316.123.4567 and I will respond to your needs immediately.

Oh, and don't forget to tell them the story of your visit - those comments are truly valuable to us in continuing to provide the very best experience for you.
