yeah, the V6 ones are pretty peppy around town, the and the SRT 392 my bought his wife a few years ago is just insane. But those are a thin minority of all the Jeeps on the road, and even those are absolutely terrible on highways.
I love Wranglers in their proper place, and I've even thought of picking up another for myself and the teens to use for local errands, strickly around-town driving.
I just hate when I get stuck behind one on any road in which I know traffic would otherwise be moving much faster. They're definitely not built for highway performance.
