I am going to stick my neck out and say that i think this new Hummer is actually smaller than the new X.

Either way, a five cylinder motor???
225hp???

And then they want us to spend upwards of 35k to get a vehicle with a Hummer name on it??

Think I'd invest in the new X first.
You'd get reliability and what seems to be more truck for the money.
