Sorry, but you'll have to settle for an 09 H2. GM has ceased production of them and have no plans to make any more. In fact, they're trying to sell Hummer but haven't found any buyers yet. And they're buying back Hummer dealerships.
So the only way to get an H2 in a few years is to find a used one. Either on a car dealer's lot or a private party. Also, you'll need to have your parents buy it and insure it since you can't sign any legal document until you're 18.
Trying to find a job so you can save up for one is impossible. Many adults can't find a job that will pay enough to afford a $60,000 vehicle. Even with a college degree. I wish you the best but anything short of winning the lottery (which your parents will have to claim since you're not 18) and your H2 will still be a dream at 16.
