GMID request and info needed please!

[Hmmm2]

I'm now seriously thinking about trading my '06 H3 in for a new '07 H2. Can anyone tell me about any real incentives out there now still be offered? I need to keep the price down as much as possible (don't we all ..lol). I love the H3 but the H2 has always had my eye. Could I a GMID from someone when needed? What % does a GMID usually subtract from the price? Any S. CA. people here .. any great dealer suggestions for getting a good price? Thanks! I know, I sound like a newbie ... but I need the facts.
