I am a Mercedes enthusiast that has owned models ranging from SL, S and E classes since 1977. I have owned 4 diesels and 8 gas mosels. This is without a doubt, the finest car yet. The speed and torgue is fantastic, actually faster than the E320 gas model. Combine this with fantastic mileage (37 MPG hwy) great handling, impressive interior and exterior design, roomy interior, large trunk and lots of neat features and creature comforts and you have a 10.
