Hi how are you?
What a great car, how are you today?
Why thank you.  I'm doing well.  I'm asking $7000 for the car.  What do you think?
That is a little steep for me , but  I can budget $4900, unless you can tell me something valuable that would make a higher price fair? 
Well I would like to get it sold soon.  Would you be willing to pay more if I deliver it to you?
If you deliver to me, I would be willing to go to $5800 to cover that price.
