My Heep is the 2.5 4-banger and that thing is a PIG...both on gas and in speed. I know, I know...it's a Jeep...not meant for speed. But man, you have to HAMMER it just to keep up with traffic, especially from a red light. I personally don't care about the abuse, as long as it lasts me 2 more years of college!!! Hell though, the power is PATHETIC.

Honest to God, my 88 Ranger STX 4x4 (EVEN when it was STOCK) would walk ALL over my Jeep in the woods in power AND 4x4 prowess!!!!!!!!!!!!!!

Long story short, get the 4.0!!!
