New Guy - Hello All

[FNGH3]

My Jeep Wrangler finally bit the dust with rust and many miles. I drove a friend's 2008 H3 last week and I loved it. I've always wanted a Hummer anyway. I'm getting ready to drop some dollars on a 2010 or new 2009 H3. I just have three questions: if Tengzhong completes the deal will I be able to use a GM dealer for warranty work or will it have to be one of their designated Hummer dealers?
If the Tengzhong deal with GM fails (which is something I think might happen and has hastened my decision to get an H3) will I be able to go to any GM dealer for warranty work on my H3 even though they've gotten rid of the Hummer brand? How well do the cloth seats wear??

Hope to be joining your ranks soon and posting some pictures if I pull the trigger on the H3.
