Questions??

[martini]

Hi all. I am looking into getting a H3 and was hoping you could help answer some of my questions/concerns.
Is it true that it can be serviced at a Chevy dealer (Hummer dealer isn't really close to me)?
What are the dimensions of the back cargo area? I play golf and was wondering if a set of clubs fit if the back seats were up.
My current car has audio controls on the steering wheel and I am afraid that I will really miss this feature, is there anything I can do/add to get it on the H3?
Thanks in advance for the help.
