| Year | Body/Powertrain | Comment |
| 2005 | 4dr SUV 288-horsepower 5.0L V8 5-speed shiftable automatic AWD w/low range |
Space is limited for adults in the back espically if the front passenger is tall. Seats are not bucket like the front so if driver takes a hard turn you go flying. see full Mercedes-Benz M-Class review |
