The H2 is a blending of 1500-series Tahoe parts with 2500-series Suburban bits (note the 8-lug wheels, usually found on 3/4 ton GM trucks). Owing to the weight of the 2500 series pieces, it's heavier than a comparably-sized Tahoe, and runs larger, heavier wheels and all-terrain tires, all of which conspire to diminish fuel economy. Not the easiest vehicle to see out of, and a rear camera is mandatory if you plan to parallel park without squishing a Civic.

As very large SUV's go, it's an inferior choice for street use for the reasons cited above. Off-road? Depends. It's weight requires a damn big tire in order to have sufficient floatation ability to handle deep mud. It should be okay in any off-road environment on a relatively firm surface, where excessive weight is not a tremendous disadvantage. Just bear in mind that the heavier the vehicle, the greater the stopping distance that you will require while driving, particularly on a slippery surface.

If you want a vehicle of this size and you want some flash, I would recommend the Escalade over the H2, as the Caddy is more economical and easier to drive on the street than the H2.

BTW, $10K? Even today, that seems super-low. Has the vehicle been reconstructed and/or a theft recovery?
