Used 2013 Mercedes-Benz M-class ML 350 Sport Utility 4D

Any luxury SUV can promise a quiet cabin and a smooth ride. But very few can claim a 174-mph top speed on the German autobahns or offer the stump-pulling torque of a fuel-efficient diesel engine. The well-regarded safety features of the M-Class are just another selling point, as is its 7,200-pound tow rating.

While the M-Class can wear many hats, it can’t fit more than five people in its well-appointed cabin. Those needing more space might look to the larger GL or even an Audi Q7 or Infiniti JX. Those seeking similar luxury and off-road features at a more affordable price might consider the Jeep Grand Cherokee Limited.
