Their web site is kinda of lame.
To see their Hummer inventory, you have to find it through
http://www.gmbuypower.com
and you can use their zip code 59102
They only show the msrp price, but the stickers show what is on each truck.
The results page shows they currently have 50 in stock.
Just tested this link, it worked a second ago.
