i remember reading a new ML320 CDI is more fuel efficient than a Lexus RX.....something or other off-roader! its great though when they badge them as hybrids....people think oh wow i am saving the environment when they really aren't lol! another thing that confuses me...while on this topic.....all the retarded greenpeace activists who act like hypocrits....they tell everyone to be green....and to drive "hybrids" but when they are on tv they are normally in a 20 year old Land Rover....LOOOOOL...so fuel efficient!!
