Need AIRstream appraisal, anybody local to L.A.?

[qdp]

this posting thing is confusing... I own a 2004 CCD 25ft Airstream that was originally used by Paris Hilton Nicole Richie in the FOX TV Show: A SIMPLE LIFE: Road Trip, I, and II.

Basically brand new, unused, it sat on my lot as an office (construction remodel to my house) until a gal plowed into it, totalling the write off. Now my insurance company claims it has no higher value than a reg. unit./

I need a referral to a knowledgeable appraiser who can value this unit based on the celebrity factor and get the insurance company to ante up.

Any suggestions, links. I have one contact with Sotheby's but they are off the charts on what this could fetch at auction. I think I need someone reasonable.

thanks, Quentin
