Mercedes-Benz M-Class 
The most affordable ML comes with a diesel engine, which is the most popular engine type. There are three other possible engines for the ML, including a 302-hp 3.5L V6, a 402-hp 4.6L V8 and a turbocharged 518-hp 5.5L V8 for the powerful ML 63 AMG. The ML quite literally invented the mid-size luxury SUV segment and is as charming as ever.
