I received my '04 e500 4matic in January, and absolutely love the car. I had the radio static problem after about 1 week, which the dealer replaced very quickly. They came and picked my car up (50 miles) and left me with a c240
4matic loaner. Overall, the car has been great in ustate NY weather, even with the stock Conti tires. Mileage has been fair, 18-20 all around. Navigation system (dvd) is much better than the one I have in my '03 clk430a, but still not as good as the ones in a Lexus. Incredible power; it was tough laying off the accelerator for the first thousand miles, though I'm sure the engine will be better off because of it. Active seats are awesome. My car didn't come with the active cornering lights as promised; I've written to MB directly on this. I am very pleased with this automobile, and would highly recommend it.
