DO NOT GET A 4 BANGER UNDER ANY CIRCUMSTANCES. I had an 04 wrangler before my car smart days. I thought cool 4 cyl. good gas. WRONG it gets about 20 mpg on the interstate, the only time I can let the gas pedal off the floor is going down hill, you must constantly hear the whine of it's incompetence because you have to run the rpms high, changing gears on even the smallest of grades, and i had stock 27's on it. My 1990 xj w/ 130,000 gets the same gas millage as that POS 4 banger and it has 31's. Also my 4 banger completely melted 2 spark plugs and blew 2 CAM posistion sensors, so for a few weeks was only running on 2 cyl. and had a crazy mis untill about 2700 RPMS. Luckily it was still under warrenty, as soon as it was fixed it got sold. For your own good, take everyones advice and don't even consider a 4 banger.
