Guest UB DAN, I suggest you go back and read my note again. Nowhere did I say that Jeeps are ok and anything bigger is not. It does not do your case any good when you twist other peoples' words. I dont own an SUV. I drive a van with an underpowered 6 cylinder engine. Nothing that runs on fossil fuel is "ok" but, for the time being, we are stuck with them. Some idiot from Ford was on the news last night claiming he gets over 18 mpg with his monster suv. BOLLOX!!
