I want to trade my range rover, which is ***** on gas, for a 2005 benz e320, which is diesel powered. from what I can see the cost benefit of diesel, especially coming from a rangerove, will be significant even though diesel is like 10-20 cents more per gallon in ny state. I drive a lot too so I am thinking this could be worth it. I need to get back in a benz. I like my range but I've been missing my slk ever since trading.
