Evan,
Everything in life is negotiable. Don't let anyone tell you any different.
I had a problem with the drivers seat in my car rocking back and forth during accel/decel when I first got it last spring. It was a couple of months out of warranty and through some persistance I got Donway Ford to pay for most of the $400 repair. I only covered $50. It wasn't easy but I did it. I'll drop you a line later on in the week when I have some time and come see your ride and tell you more then.
Richard
