DO NOT use Kelly Blue Book for negotiations.
Use the NADA website.

According to that link the car's NADA blue book is $12,675 average retail, $10,650 trade in. $8990 is a damn good deal.
If I was in the market right now, and I saw that car independantly of this post, I'd already have bought it, dude.
