The 2018 Mercedes-Benz E400 is praised for its luxurious quiet cabin, balanced handling, and advanced features like massaging seats and a panoramic sunroof. High maintenance costs and a dated infotainment system are its main drawbacks, but it delivers an exceptional blend of performance and refinement.
