I have been into 4wd competion's for 10 years and have seen most makes and models having there go. Unfortunatly as far as Jeeps, well they cost a lot to modify (but yes so do most) but they also break real easy. A friend of mine is finding this out right now. He wants to run 33" tyres ARB bullbar and front and rear lockers. ARB said to do this correctly it will cost him about $15k. I have one of the most modified Suzuki's in Oz that is still street legal and will say yeah I spent a lot to get it to this level, but no were near as much as other brands and have won most events I've entered (one event I'm still the only registered car to of completed). As for being easy to roll I guess they all are able to roll but I never have and as you see in my pic it gets good angles.
