We bought this vehicle to replace a very good Yukon. I must say, the ride quality of this vehicle is extraordinary. It is the quietest and smoothest vehicle we have ever owned. I love the panoramic roof and the limousine seating in the second row and the fold third row provides a very spacious storage compartment. I am not a big fan of the complicated stereo setup but we are learning new things about the vehicle setup every day. The stereo sound quality is really good and the interior materials are really nice quality. The seats are very firm like most Euro cars and we really like that as well. Fuel mileage is around 18 to this point and that is without any highway driving. We have two complaints about the car. The wheels are simply ugly and that is a taste thing and the GPS system is dependent on a disk that must be updated to the tune of about 300 bucks. The GPS disk goes into a DVD player that is not set up so you can actually watch DVD's as well. I think that would have been a nice plus to use the center console DVD as an actual player and not just a disk reader for GPS. I will buy the next model when it is time to get a new vehicle.
Had the R350 for about a month and it is excellent in all ways. We needed a 6 to 7 passenger vehicle that was NOT a minivan and there was nothing from Ford, Chevy, Buick, BMW, Lexus, etc that has the legroom in the third row, sliding second row seats, and legroom for my long-legged crew. All of the other vehicles we looked at had a joke for a third row. I can also attest to the safety of the vehicle. After owning it for 5 days my wife was hit directly in the rear wheel by a gal who ran right through a redlight without braking. It damaged the quarterpanel slightly and the rear bumper side and suspension, but totaled the other gals car. Several of the body shop guys commented that this car is built like a TANK! We have it back and it is perfect for our family. All six seats recline (a little less in the third row), the huge glass roof panels are awesome for road trips, the stereo is superb and the all wheel drive give me confidence when conditions change. I might buy another for me. This one is my wife's!
I have a 2006 R350 I have had for almost two years. For a MB I would expect more quality. I had the drivers seat belt latch replaced at a cost of $450, at this time the vehicle was out of manufacturers warranty. Approximately 1 month after I had it replaced by a MB mechanic but not a certified warranty mechanic, I received a letter from MB stating the recall of the latch. Do you think they would reimburse me? No. this is something they can improve on. If you hear a whining noise coming from the engine, replace the idler pulley at a cost of $60 yourself along with the serpentine belt. I just replaced the liftgate lock/latch myself at a cost of $160. I will need to replace the sunroof motor myself at a cost of $260. Be careful with the sunroof switch, if it breaks, it will be $500 for a new because it is not sold separately it has to be sold with the console. I fixed mine with a little ingenuity. ($0) I change my own oil which needs to be sucked out from the dipstick tube. If you can do this yourself you"ll keep the authorized dealers from sucking your money and talking you into things you do not need at an average cost at the dealer $400 each oil change!! My total costs are $65 for oil change as this car needs Mobil 1 Synthetic, the oil filter is right on top of the engine, not the bottom, easy access. Also, you need to figure out how to reset the service indicator. If you do not fill with correct amount of oil, ( 8.5 US quarts) the check engine oil light will also alert, This does NOT have to be reset. The check engine light comes on an awful lot if the gas cap comes loose. I clear this myself with my own computer analyzer. ($250-$300) Just saying, if you are not mechanically inclined or fear this sort of auto work, do not buy this car. Lastly, I am sorry, but Continental tires are terrible for this car. I always thought tires should last more than 20k miles. They do not grab the road for effortless cornering. I put on some Nittos, best tire for a european car. Waht a difference they made in cornering and handling, Before the Nittos, my '03 Ford Explorer handled better than this car. BTW, I still have the Ford, 187k miles, perfect shape. I bought it new. I purchased the MB with 25k miles and now have 65k. Oh, do not opt for high dollar xenon bulbs, you'll replace them every 2-3 months. The Harmon Cardon stereo is excellent.
