Hello
Hello. Are you interested in my car?
Yes I am. How many miles are on it and is it in good condition?
There are only 29k miles. I'm the original owner and it has been well taken care of. 
Excellent. Can you lower the price at all? I do not want to pay the full price you are asking.
Well, I could yea. The car's maintanance has always been handled by my Chrysler dealer and it is freshly detailed so I don't want to go much lower. 
Okay. How does 9000 sound?
Woah. That's too low for what the cars worth. What about 13000?
12000? That could work for me
It's a good deal and a good car
