I hate to break it to you man but the H2 is not inexpensive to maintain.
Some parts are from the GM parts bin. The the Hummer specific parts are going to run you some $$$

An H2 is actually very expensive to maintain. Between tires (stockers last a long time but you will be lucky to get 35K out of a set of offroad tires) chassis parts, and gas you need to be ready to pay up.
