i'll have to agree with Mace. The H1 is awesome, H2 is a Suburban with a mutant body kit, and the H3 is even more of a disgrace to the Hummer name. Seriously, if they wanted to make a smaller HUMMER, they should have just made a smaller hummer, not just get a hummer-esque body line and stick on one of the other Chevy chassis.
I seriously considered an FJ Cruiser, but wanted the additional seating capacity.
I have driven the H3 and they are slow but I think off road they are not bad. The 4:1 transfer case kicks ass as does the rear locker. They should have made an option on the FJ for a lower transfer case gear. The interior is not the quality you would expect in a vehicle that costs that much but then neither is the FJ in my opinion so I guess its all up to the buyer.
I only make reference to the FJ and H3 because I considered them both before I got my 80
if you'd wheels a colorado or a trailblazer...well...you can wheel the H3. Personally, I don't think much of them on the trails...but...on the street, I suppose they're as good or bad as any other vehicle.
We passed a GM crew of engineers, sales types, execs, and a support team taking the H2, the then unreleased H3 and a couple heep rigs on the rubicon trail...they spent quite a bit of time wrenching on the rigs (from what the support team told us on their last day on the trail).
I try to stay open minded, but I would never trust one of those. You peek in over on one of their forums and 90% of the threads are about problems, trips to the dealer, etc. Even if they were reliable, guys are breaking front and rear diffs on moderate obstacles. No thanks.
