I have owned several Mercedes-Benz from 280SE to a C240 4Matic (wife's car) and this is my favorite. Wonderful creature comforts and city driving manners, but that's NOT why you would buy this car. I just took it to High Plains Raceway to get acquainted in a controlled environment. This is a heavy car, but handles extremely well. Well-balanced, good turn-in, good feedback, controllable through the limits of adhesion, fun to throttle-steer (with traction control off). Though half a ton heavier, it held its own with M3s and 911s. Next trip is to the dyno to verify HP - this car is better than advertised, even with almost 100k miles!
Great balance and power. 302 hp? This car is much faster than my BMW 540i, which is rated at 305 hp. Balance. This car has less understeer than my BMW E36 track car.
