Don't know the auction owner, but thought I'd share it because it's a good find if you are going to get the Yakima system (costs $50 new)
I just bought a couple of bikes and needed to get a transporter. I was going to get the Yakima system but decided it was too much money.
Instead of getting the Yakima system, I went with the Saris Bones 3 rack...found one via froogle for 99...
