The Car Connection's Take
TCC Rating
8.6
7.4
TCC’s Bottom Line
It ain’t cheap, but the 2009 Mercedes-Benz M-Class deserves its place atop the luxury SUV echelon. The 2008 Lexus GX 470 brings off-road credentials to the Lexus brand, but its skimpy rear-seat room and sluggish performance tarnish the image.
