CONSUMER RATINGS & REVIEWS

What real people are saying about the
2008 Mercedes-Benz R-Class R320 CDI
4dr Wagon AWD (3.0L 6cyl Turbodiesel 7A)

2008 Mercedes-Benz R-Class R320 CDI Review: "The only green luxury family utility vehicle... We get all the 4WD benefits that the SUVs bring and most of the family comforts of a seven-seater van... Pay the additional $1,000 for the diesel, and you will not regret the fewer trips to the gas station. It's a little noisier and slower up to the 20 mph zone, but after that, you cannot differentiate from a gas engine."

Favorite Features: "A lot of room inside, great seating, especially the third row."

Suggested Improvements: "The trunk is rather small. We have two kids and their strollers eat into the trunk if we are fully loaded with 7 passengers. However, that did not stop us... We just decided to change the way we pack...more soft bags."
