Nothing.
My Hummer H2 wasn't family friendly. I traded it in for a 2005 Suburban with 4 wheel drive, and am delighted to say that it was the best move that I made. Believe me, my wife, the kids, and the dog absolutely adore it! It loves the snow, is extremely roomy, extremely comfortable, and loyal. Trust us, if you are looking for a sport utility with 4 wheel drive that can seat up to 9 people like this one does and can both tow a boat, and carry the family all in one shot, look no further. You'll love it to death!
Uhhhh...the Hummer H2 isn't ANYTHING friendly. Be glad you're rid of it. Newsweek just did an article on how Hummer has become the most hated vehicle on the planet. They rented one as a test, and people gave them obscene gestures and scratched it with keys. They took it to a car dealership to get an idea of trade-in value and they were told "I'll trade with you for $25,000". When they asked the price of the new car WITHOUT trading the Hummer, they were told "$25,000"!!
On the flip side, a survey in USA Today of 3-year-old large SUV's shows the Suburban holding more of its original purchase price than any other large SUV (including the grossly over rated Toyota Sequoia and Nissan Armada). Congrats on the Suburban. They are awesome vehicles. Members of my family have put hundreds of thousands of mile on these things. My only complaint is that they are so big that even with the most powerful V-8 they are still way slower than our 4-cylinder compact.
