At the recommendation from another member (thanks Jason), I also went to Kolbe Honda in Reseda. They low-balled me on my trade-in as well. I think it's pretty universal. The blue book value of my 1997 Jeep Grand Cherokee was about $7,500. The dealer was offering $3,750 to $4,750. It sounded like they probably couldn't do better than $4k though.
Have you tried a private sale? I listed my Jeep in the Recycler and got a call a day later. I sold it for $6k.
Just keep your options open. Oh yah, and don't be an idiot like me and sell your car too fast otherwise you'll be car-less while you wait for your Pilot. At least for me, I only have one more week to wait.
