In rural CT the roads are slippery in the winter making 4wd a must. After test driving the Acura RL, Audi A6, BMW 540xi, Infiniti M35 awd and Lexus gs350 awd, I decided on the Mercedes E350 4matic. The Japanese have better electronics, the BMW cornered the best, the Audi was attractive and competent, but the Mercedes looked and drove like a true luxury car with 4wd. It's a pleasure to drive.
Great looks. It's built solid as a tank. Navigation system and satellite radio are very user friendly.
The 4matic only comes with a 5 speed auto which lowers gas mileage. It could use a little more power off the line.
