Hi are you interested in this car?
Hello. I'm interested. HOw many miles does it have on it?
20000 miles
That's great for a 3 year old car. Do you have the Carfax report?
Yes I do. 
Any major repairs?
no haven't had any issues with it. 
I would like to come by and test drive it. I only have about 10k right now though.
Sure you can come by anytime just let me know what day and time! 
Would $10,000 be good enough?
okay I can accept that. 
Great.
