Sounds like you are in a contract, not a lease. Right?

If a contract, you might try advertising the vehicle, finding someone that will take over your payments.

OR, GMAC will not care if you trade or not, as long as their loan is tied to a title in their hands. You will have to shop dealers and find one that is interested in putting some real hard money in your H3.....usually, its a dealer that is not a GM dealer, but the competition cause they usually want a GM vehicle sitting on their used car lot.makes them look aggressive...good luck.
