The Car Connection's Take
TCC Rating
8.0
8.8
TCC’s Bottom Line
The 2009 Mercedes-Benz R-Class is unlike any station wagon, minivan, or SUV currently on the market, and with the new BlueTEC model, it can haul six in supreme comfort at 24 mpg. The 2008 Audi Q7 puts a sport-ute premium on its beautifully made interior, seven-passenger seating, and sedanlike acceleration.
