The 2015 Mercedes-Benz M-Class is one of the most refined, most comfortable, and safest luxury SUVs available. It's also surprisingly fuel-efficient -- especially in ML250 BlueTEC diesel guise. The M-Class' interior has much-improved materials and detailing compared to the previous version, and it's now one of the most lavish cabins in its class.
An off-road package for several different modes of trail driving is available and allows for ground clearance of up to 11.2 inches and a water-fording depth of 23.6 inches. The package also includes a locking center differential and a 2-speed transfer case.
