Hi, are you seriously interested in purchasing my bmw?
Yes.  It looks like a great car. I actually have a 2002 BMW X5 SUV that has all wheel drive.  I would be willing to trade you that plus $5000 cash.  This way you get a great running truck that can handle the mountains and some cash in your pocket.  Deal?
It sounds good but what's the condition of the suv?
The SUV is in great condition.  I had new tires put on last winter.  I have a Carfax report so you can see that it hasn't had accidents.  The main reason I want to get rid of it is because I want better gas mileage with a car rather than an SUV.  So do we have a deal for $5000?
Make it 5900 + the suv and we've got a deal.
Deal!  Thanks!
