Hello, I am interested in your Chevy. I see that you are asking $5,000, is the price negotiable?
I have a little wiggle room. 
Is there any body damage?
No, it is in really good shape.
I have looked at comps and I am willing to pay $3,000
I couldn't go that low, I would drop the price to $4,500 for you
It just doesn't appear to be worth $4,500. Would you be willing to take $3,500
I assure you that this is a nice vehicle and is worth the money. I am needing cash so I would go down to $4,000
I only have $3,800 but I have it in cash and can be there in a couple hours.
$3,800 if you are here in a couple hours with cash.
