Hummer Guy or H3Builder can set us straight on this, but it is my understanding GM bought the name and distribution rights from General and also provides engines, frames and subassemblies through their providers, such as American Axle but AM General does the assembly on the H2 in Indiana and provides limited components. I don't think AM General provides anything for the H3.
The big cost here is distribution, maintenance and parts and GM felt its dealership network would boost sales when they bought the brand, and initially they did. We all complain about "stealership" prices, but it costs a lot of money to maintain the infrastructure for a vehicle that is sold throughout the US and worldwide.
I believe we know nothing about the real Hummer goings on right now. I feel strongly it was a mistake to announce the brand up for sale publicly and thereby crippling dealers.
