Not trying to be a dick but your KBB is wrong. i just did it with 200k miles and here it is so i posted the link also.
excellent $5,305
good,$4,780
fair,$4,130

and with a second gear grind this car would fall under good or fair. So the book on it is under $5,000 not $7,000. This is a private party sale not a suggested retail value (is what you posted) also if you click private to get $7,000 the car would have to have 80k on it for that sale price.
