I was in the Verizon store today to look at / buy a car bracket and/or desktop dock. They were out of desktop docks, but had the car bracket for $29.99 (not bad, in my opinion, the quality and fit is great, and it doubles as a belt clip), and it was discounted down to $22.49 for some reason.
Hope it helps!

Edit: Here is the car mount (Not a powered dock, just plastic and rubber, and the holster dismounts and has a belt clip on the back):
