It is hard to believe that is has already been a year since you purchased your new vehicle from me. You may be due for scheduled maintenance or an oil change. If you have not yet made an appointment, please contact our service department to schedule your maintenance appointment. It is important that you keep up with the factory recommended service in order to keep your factory warranty valid.

Let me know when your vehicle will be in for service, and I will be happy to follow up for you and ensure that everything is handled properly.

If there is anything I can do to further assist you while your car is in our service department, please do not hesitate to contact me.

Once again, if you know of anyone that is shopping for a new vehicle, I would greatly appreciate the referral and you can be assured that they will receive special treatment.
