once you get to the laramie(or higher), they make you get the diesel or the hemi... the sport can only be had with the hemi... bit annoying for sure, but i find most people opting for those levels of trim aren't as worried about fuel usage when it sacrifices capability.
and red, yeah... the grand cherokee is great. i hate to get all fanboi, but we really are making the best cars sine i started selling them almost 16 years ago... there are quite a few that i am happy about, but those two are my top picks...
