Check engine light...like everyone else, BUT!

[MaxH3]

While the cylinder head is not the best news, its no sweat because of the warranty. But that leads me to this observation.

Through Enterprise Rental (covered by Hummer, of course) I have a 2007 H3, base model with no bells or whistles at all with 9k on the odometer. We have a LUX 2006 H3 with leather and all the "stuff" with 12k. Can someone tell me what changed with the 07? It rides nicer, has a more responsive throttle, quicker from a dead stop, the list goes on. It feels more solid too. How can this car feel so much better? Is there something I'm missing here? Can the techs make mine quicker...smoother?

Thoughts?
