Hello
Hi, I'm interested in your Kia Rio. 
Awesome, do you have any questions? It is in really great shape, we have taken great care of it.
I'm offering $2450 but I am willing to negotiate
Alright, I'm willing to negotiate as well, but $2450 is pretty low. Do you have any questions about the car itself?
How long have you used it for?
I haven't had it long at all but my Grandmother had it before me and I know firsthand that she had it professionally serviced only at the dealer and it has been perfectly maintained, no accidents or anything. 
Okay. Does it include a spare tire?
Yep, it does. Also, never been in an accident, and has a clean title.
Okay. I'm willing to pay $2800 and nothing less.
Alright well I'm glad you're not willing to pay any less than that, but I'm afraid you're going to have to offer a bit more...
$2825 is my final offer.
