I was selling my 2000 Black Celica GT (auto) last year in July completely stock (had nothing done to it, to keep the value up) for $11,000 according to KBB.Com, but I wasn't getting too many hits off of that. I lowered it to 10,000 and I instantly got a lot of hits.
I had enough miles where it was roughly around 14,500 per year average which brought down the price of the car a little along with the color of black. The dealer would only give me MAYBE $6000 for the car... and that was a major "Hell No!!" so I sold it privately for 10,000 with ease. It was a little bigger pain in the arse, but so much worth it since half of that went for the down-payment of my new Celica GTS.
