Hi Gloria, I'm calling from the car on my way to the meeting. I would like to make an appointment to get my car into the shop. 
Sure thing Mr. Jones. Let me place a call into INtelligent Auto Solutions.
Thanks so much Gloria. The sooner you can get it into the shop for an appointment the better
What is the make and model of your car
It's a 2015 Mercedes Benz S class
Ok. Got it. What should I say is wrong with the car? 
It's making a weird noise as I press in the brakes to come to a stop.
Ok. Got it. Anything else i should know before I call in. 
It revs really high first thing in the morning when I go out to start it. 
That sounds really weird. Do you feel safe driving the car?
Yes. I think so. I am able to come to full and complete stops and the seems to be handling pretty well. 
Ok. I am calling into the shop now. I can see their schedule for the next few days. When is the soonest you can bring the car in?
I can bring it in either tomorrow or the following day
Would tomorrow at 1PM work for you?
No. I'll be in a business meeting at that time. Do you they anything sooner. I really want to get this checked out. 
Oh. I see that they just had someone call in to cancel their 8AM appt.  
An 8AM appt. would work really well. Is that for tomorrow?
Yes. Tomorrow at 8AM. What should I leave as your contact information
