Hello do you still have this car?
Yes!  It is still available and I'm interested in selling!  :)
Can you tell me anything about it
I am the original owner, bought it new in 2006.  Great vehicle - has never left me stranded.  The interior is nearly pristine and the exterior looks very good (some dings like you would expect from an 11 year old vehicle).  Still drives great.  Only 85,000 miles.
Ok, how much are you asking?
I'm asking $7800.  I bought a new Escalade and no longer need this one.
Ok, I will offer you 4600 for it.
Uh, no.  Book on it is $8300.  I'm already below that.  I'd be willing to consider an offer that is more reasonable, but $4600 is over three-thousand below my asking price.
Well to be honest I found the same care with less miles for cheaper.  If oyu are willing to throw in a warranty and deliver it for me I will offer more.
OK, I can offer a 1 year warranty and will bring it to you, but I need you to make an offer.  
Best I can go is 6900
Make it an even $7000 and you have a deal.
