When a line of vehicles nears its 70th year of production, you know they’re doing something right. Such is the case with the Mercedes-Benz E-class. This line of full-sized cars has remained in-demand around the world since 1953, with no signs of slowing down.

A good carmaker continually updates even their most popular vehicles with the latest in tech, comfort, and performance. Mercedes-Benz is without a doubt, a good carmaker.

This cabriolet shows its commitment to comfort with rear seats designed to accommodate actual adult human beings. While the backseat of most convertibles is often little more than a place to toss your duffle bag, Mercedes-Benz gave rear seat passengers ample room to sit back and enjoy the ride while luxuriating in cabin comforts such as rear climate control vents and heated seats.

Mercedes engineers have done everything in their power for you to maximize the drop-top experience. Harsh air gusts at highway speed are neutralized with the AirCap system, which directs outside airflow over the vehicle’s cabin. And for those sunny but crisp days, Air Scarf technology blows warm air from the tops of the front seats to your neck and shoulders.

The already legendary Mercedes technology continues to impress. Cabin readings and infotainment are displayed on a beautiful 12.3-inch horizontal dashboard screen, including smart phone compatibility and navigation. And the tech gets even more impressive on the open road. The Autonomous Driving feature lets you take your hands off the wheel for up to two minutes at a time, at speeds up to 130mph. Motion sensors, cameras, and radar keep your E400 between the lines until the car finally reminds you resume full control. At 130mph, that’s probably a good idea.

Performance is smooth and refined, as the twin-turbo V6 glides through each of the nine gears like a snowboard down a slope. This cabrio hits highway speeds from a standing start in a more-than-respectable 5 seconds flat. You’ll have no problem passing lesser cars and slow-moving trucks conspiring to keep you from reaching your destination. Step down on the accelerator, zoom by, and enjoy the unobstructed view the way God intended – with the top down.
