First off, if you've found a sammi for $500 that runs, drives, and isn't rotted away...buy it for god's sake!! As far as the MPG's go, I'm getting about 25 on back country roads in my sammi. It's spoa'd and has a 1.6 16v (which, by the way is what I would recommend for and engine mod) Real_Red_Wagon is boasting over 30 in his stock tintop I think. Lets put it this way, your not going to find a better 4x4 on gas, regardless of whether you want to wheel it or not and your not going to find another 4x4 that will be anywhere near as capable on the trail for anywhere near that little of $$. I mean, even if he doesn't want to mod it out, just buy some decent tires and he could wheel with you and at least keep up it most places. Am I wrong???
