H1's are Awesome, Like no other however maintenece and pop-up issues are EVERY DAY it seems. My brand New 2001 H1 at $119,000 had Rust on it straight from the dealer. If you have a Warranty you are all set if you are out of warranty like my other H1's it will cost you a tom of money to keep the truck running like it should. Now for me Iam a bit of a wierdo when it comes to air leaks or fluid leaks so I spent a ton of money on CTIS issues and drive shaft leaks. ALl in all I love the H1's but lack of space for passengers, maintenece and people constantly booing you made me go in and out of the model. I have a family of 5 so space was definetly a commodity that the H1 didnt have.
H2's Luv them however I need more of a usuable truck and that has lots of room and can take a beating. No offense to the H3's but the H2 interior is as nice as my escalade and I dont feel I can beat it up:-) I love my H'2 but use the H3 more for what I feel Hummers are intended for.
Off-roading. Hands down my H3Alpha out wheeled my H2 and Iam a certified off-road instructor. It was the closest thing to my H1 that I have ever off roaded in in any terrain. (
H2 owners dont hate me its just a reality) Not to disparage H2's in any way shape or form but the H2 is just a little to big, high and awkward to get out of alot of situations. I have broke more rear and side windows in my H2's trying to get out of tight spots than I can count on both hands

. The offr oad instructors and I all agreed that the H3/H3Alpha were superior to the H2 in certain but NOT all off-road terrains. Please note my AlphaH3t also has a sweet FRONT LOCKER. Hope this answers your questions. I could go into pages of detail on all the vehicles and models that hummer has made. I owned all of them at least twice and plan to NEVER be without one.
Thanks agian for the assist-Peter
