You probably don't wan't a Jeep. I don't know of any that are fast and powerful, or gets good MPG.
The 2.5 and the 4.0 are horribly inefficient engines. That's why they get such poor gas mileage. My swap should get me about 20mpg. Not that that's worth the swap or anything. HahIt's hard to find v8s in wranglers, plus they use SO much gas specially with a jeep. My 2.5l gets like 15-19 city miles and 19-22 highway haha and that's just a four cylinder! You think the 97 Sport is worth it? I don't know to much about sports are jeeps in general haha
