Hi! You were interested in the Ranger?
It looks nice, but I really don't think it's worth what you're asking.
How come? It was very well maintained through our company, everything runs perfect on it. Just like new.
It's 6 years old and that mileage seems high. If it was a company truck that could mean a lot of wear and tear. The engine and trans could go out at any time
The company has maintained it very well, the transmission shifts good. As you know even a high mileage truck, if maintained well, will last you forever.
I understand. But even with it being maintained well, these things are going to happen. I'll offer $4,000
4,000 is too low. I'll be willing to give you a 1 year warranty on the engine and transmission if that's what is concerning you.
I'll come up to $5,500. With a 2 year warranty
I'm sorry, I'm willing to work with you but $5,500 is not acceptable. How about $8,000 with a 2 year warranty. We'll even throw in a toolbox for the back! 
Definitely can't do 8. I'll do $6,300. That's my final offer.
