A proper diesel estate car like an MB E220d has a more usable cargo area than the typical SUV, rides comfortably and efficiently on the highway consuming less than 5 liters per 100 kilometers (fuel tank range is over 1200 kilometers), and has state-of-the-art safety technologies. In comparison, a SUV just gives you that extra confidence that no matter the weather conditions, you'll make it to your end destination because of the increased ride height, bigger tyres and 4WD systems. For most people that may be 2 or 3 days during the year, and the rest of the time they are paying dearly for this inefficiency.
