Hi!
Hi I'm interested in this car
Great. It is in awesome shape.
It's more then I would like to spend though
How much are you wanting to spend? 
umm I was thinking around 2660$
I could do 3200. It has new tires.
well, that's a bit high...
I feel based on kelly blue book it is a fair offer. I have put a lot of work in this car to get it in great shape.
Are you good at detailing the inside and outside of cars? I'll pay 3200 if you throw in free detailing for the next two years, at least twice a year.
No. I can't do that. I will get it professionally detailed before meeting you but that is it.
okay then I can only do 2950
I can do 3000. That is the absolute lowest I can go. 
okay deal.
