2010 Mercedes-Benz M-Class

Price Range: $45,700 - $91,050

The Mercedes-Benz M-Class is tough enough for light off-roading and has serious towing ability, yet it's spacious enough for four or five adults and has a smooth ride. With the new ML320 Bluetec diesel and the upcoming ML450 Hybrid, the M-Class lineup will have become much more fuel-efficient without sacrificing performance or capability. But for those who want top performance, the ML63 AMG, with its 503-hp V8 remains the king of the lineup.
