Whats this Worth?

[HUMMERDOGG]

You'll be shelling out at least $5K plus for an extended warranty (if you can even get one at all) and the ac upgrade will cost you at least a $1K, and I have heard as much as $4K. You definitely need to shop around for both...

Regarding the A/C upgrade either one of these guys should be able to lead you in the right direction:

Chuck Kopelson who runs www.flashoffroad.com
Dave Breggin with www.BlueHummer.com

Regarding the Extended Warranty:
Dave sells it at his website-
http://www.bluehummer.com/exwa.html

And Ben actually owns the company:
http://www.exoticwarranty.com/

Try these websites:

To Possibly Purchase the upgraded A/C:

Hopefully this information helps. I'm right with you as I continue to look for that perfect Hummer Wagon...

Thanks.
