Audi A6

Below are the specs of my car. I am looking to get what the blue book value is: $22,000 or best offer/negotiable/forced to sell. It has approximately 83,100 miles on it. I have all the records of maintenance prior and during owning the vehicle. I also purchased brand new Continental all whether tires this past fall and there is a spare rim and tire in the trunk.
