I just took the same car and changed the mileage to 100000. Look how it changed the price? So I would say KBB does account for mileage. Not sure where you got 7800 but in real life your car books for about 5000.00
full out retail only applies to collector cars and perfect non repainted cars with no damage ever in its history. Not to march on your parade just answering your question about no one wanting your car.. Good luck with your sale!!!!

This vehicle has a clean title history , the paint, body and interior have only minor (if any) blemishes, and there are no major mechanical problems. There should be little or no rust on this vehicle. The tires match and have substantial tread wear left. A "good" vehicle will need some reconditioning to be sold at retail. Most consumer owned vehicles fall into this category.
