Hi I am interested in your car, could you tell me if their is anything mechanically wrong with it
No check engine light on. It's in solid running condition. 
Great. What about dings and dents? 
Typical wear and tear on the body for the car being fourteen years old, nothing too unreasonable. 
Ok. I really need to get a second car for the household to use , would you take 3400 for it?
If you have all cash I will take $3500 for it. 
Cash it is, great! I can come pick it up tommorow
You have a deal.
