This is Mercedes doing what it does best: building a highway cruiser that wraps you in a quiet, refined cocoon while the miles disappear. The inline-six in the E450 delivers the silken power this chassis deserves, and owners who maintain them properly report 200k+ miles without drama. But if you're shopping used, generation matters enormously. Diesel models across multiple eras suffer AdBlue injector failures that clog systems and trigger check engine lights. Older examples need diligent maintenance or they'll punish your wallet, and the four-cylinder E350 feels like the wrong engine in this car. The current W214 generation earned genuine acclaim (Car and Driver's perfect 10/10, MotorTrend's 2025 Car of the Year), but you're still paying luxury repair bills to keep any E-Class running right. Buy the six-cylinder, keep up with services, and you get a car that genuinely elevates highway driving above the BMW and Audi alternatives.
Standard all-wheel drive in a compact hatchback makes this the default choice for snow-belt buyers who don't want an SUV, but Subaru killed the $22k base trim, so now you're starting at $27k and wondering why you're not in a sharper Civic or Mazda3. The real problem is internal: the Crosstrek is the same car with a lift kit, and it outsells the Impreza by a landslide because ground clearance photographs better than handling does. The powertrain feels a half-step behind rivals, the infotainment lags, and if you live somewhere it doesn't snow, you're funding capability you'll never use. Buy this if winter traction matters more than driving enjoyment and you genuinely prefer the lower center of gravity, otherwise, the Civic is quicker, more efficient, and costs less to insure.
