On the “storage wars is fake” thread awhile ago I had to do a search to see if Barry’s cars were his or not. Looks like he owns a bunch/most of them - and motorcyles. Seems Barry earned his millions in the grocery produce import/export business!
The episode with the Decoliner had the designer/builder (Grub) in it as well - so I imagine it was just on loan (good promo for Grub).
Here’s a link with some photos of Barry’s cars. Lots of annoying ads, but my software protection didn’t warn me of anything bad.

On March 25, 2012 it was announced that Barry Weiss will be getting his own A&E spin off show called “What Are You Worth?”. Casting has just begun for “What Are You Worth” which will feature Barry helping cash strapped families make extra money. Further details on the show have not been released yet but insiders expect it to be similar to ABC’s Extreme Makeover series which helps families by providing them with entire new homes.
