what is the mileage on this vehicle?
Hello the vehicle has low mileage it gets 27 mpg in the city
i'm on a budget. this car is a few years older, would you be willing to accept $10000
That is half of lsiting price, while I am open to negotiatons I cannot go that low. This vehicle is fature loaded, and is only 2 years old with a single owner. 
looks like it could use a tuneup, if i do the tune up, will you give it to me for 10500?
Unfortunately that is far too low I can give you a reduction but not at half the price. Keep in mind car has all service records, and is like brand new. It even has smart device integration, adjusable lumbar support for the drivers seat, and aluminum wheels. The absolute lowest I could go would be 18,500 and you would have to come pick it up with cash in hand.
I can only go as high as $13000, can you do it for that price?
That is too low for a car that is 2 years old, do you have any other negotiating leverage or maybe an old vehicle you can throw in?
I'll throw in my 1996 outback if you give it to me for 13000
That sounds like a deal to me
