You'll get sucky gas mileage with the inline 6 as well, sorry to say. My wife has a 98 Cherokee Sport, and she might just hit 20 mpg on a long highway trip. Four-wheel-drive gulps down the gas even faster. She had a 95 Wrangler before that. Jeeps are great, sturdy vehicles that don't ask for much in terms of maintenance or repair, and they're not too primadonna-ish so that you're afraid to get in one with muddy shoes..
