I just traded in my 320 CLK and my BMW 525i for a 2004 E500. This is my 3rd E class as I previously owned a '92 400E and a '01 E430. I loved my 400E. In spite of its 195mm tires it was a true drivers car. My '01 E430 was not as delightful although it was a very nice car to drive. My new E500 is simply remarkable. The semi active air suspension allows you to choose between a beautifully controlled marshmallow ride and a typically firm Mercedes ride. The handling is exceptional, squat dive and roll is unmistakably absent. The structure is rock solid as usual. Does anyone know what the resonant frequency is for the new structure and how the figure compares to previous E class models? The extra 21 horses and additional torque of the 5 liter engine along with the 7 speed automatic equal a level of performance never before seen on non AMG models. My first freeway onramp was controlled by a traffic signal. I was surprised that a 1/4 throttle opening resulted in a huge chirp of the Conti's followed by rocket ship acceleration. The sound effects are lovely as well. Options can be kept to a minimum without sacrificing luxury. My only options are the entertainment package and sunroof.
I highly recommend giving the E500 serious consideration. I bought mine from Keyon (I am probably spelling it her name wrong) at W.I. Simonson in Santa Monica California. I was very happy with my buying experience.
