Hi there
Hello! I am possibly interested in the car for sale. 
sure thing what do you need to ask?
When was the last time you had the car serviced other than the oil change?
about a month ago 
Has the car been in any accidents or have any dents etc?
no its not been in any accidents nor has any dents
What is the year and the odometer reading?
2015, and reading is 40000 miles
I have a mechanic with me and would like him to run a diagnostics on the car. If he clears it, I'm willing to pay cash on the spot. Would you be willing to take $2240?
that's too low. You can definitely have the mechanic run by it, I am willing to accept 2900 last
Can I meet you half way at $2500?
Well you will have to come pick it up yourself then at that price I can only do that
Absolutely I can do that.
