Hello, I am interested in your truck. How many miles are on it?
Hi how are you? I'm asking 6k on this classic truck. Only 457k miles on!
That is a lot of miles on that truck, are you willing to negotiate?
Yes, I'm asking 6000 but I'm willing to go down to 5, if you come pick it up. 
$5,000 is still too far out of my price range. The truck has very high miles, and looks as if it is covered in rust. I have $3,000 cash in hand. I am willing to head over now
... Well that's kind of harsh don't you think? This truck has been in my family for generations, it's a family heirloom. 3000 dollars is too low, the sale is off!
