"I have had my '07 R320 CDI 4MATIC for about 10 months now. I have about 30k miles (~90% highway). I agree with some others on here, that the OEM Micheillen tires are not very good, however I just moved up to the Continental 4x4, and I am much happier. I love the fact that I can get all I need into it and still have room for all that the wife happens to pick up on family trips. This being one of the snowiest winters on record in NH, I can attest to its snow performance. In a word, exceptional. I have never owned a better snow machine. The fuel economy also is incredible, with spring-summer values of 27-29 MPG and winter (worst for a diesel) of 24-26 MPG. I will keep this one for quite some time."
"Coming from a Durango, I have nothing but praise for the big R.
PROS: Great quality, good ride, super roomy, looks good, quiet, great stereo, nice sunroof, silky 7-speed.
CONS: Nit-pickin' here, but.. mileage is ok, but not great, V-6 is adequate, but no high-HP machine. Probably not the cheapest vehicle for what you get, but the quality is unmatched! Oh, the stigma for owning the benz can be painful at times. But it's just because others are jealous."
"WOW, drives like floating on clouds with a little horse power at your foot when needed.
Lots of room, took long trip with 2 infants and 4 adults, everyone was comfortable.
I give 5 stars on Engineering little pricy coming in at $55k."
"They call it a cross over, but its a SUV with lots of style and comfort that handles very well for its size. Six or seven adults can comfortably be accommodated for 100 mile trips. The sliding glass roof is great for sight seeing in NYC. The full time 4-wheel drive is peace-of-mind in the winter and rain. Maintenance is high, but its a Benz. The best is never cheap."
"My wife is totally enamored with the R Class CDI, due to its superb handling and passenger/cargo capacity. We also have a 17 cu. ft. luggage carrier, which is easily stored and installed for the long hauls."
