2007 Mercedes-Benz R320

The 2007 Mercedes-Benz R320 AWD wagon adds a new dimension to the R series.  This model runs on diesel fuel to give you more miles to the gallon.  Body length stretches to an impressive 203 inches.

The R320 has a 3.0 L, 215 hp V6 powertrain.  Gas mileage comes out to 21 mpg in the city and 28 on the highway.  Finally, this model has 4 doors, seats 6, and gives you a max cargo capacity of 85 cubic feet.

Overall, the critics like the 2007 R320 because it gives you the comforts of a minivan in a wagon.  On the other hand, the relatively hefty price tag and heavy doors could deter some buyers.  In any case, think of the '07 R320 as a capable crossover that combines some of the best features from a wagon and minivan.
