I bought this vehicle with 132K miles on it from a mechanic that had owned it for 5 years.
I had it in my possession for a little over a year.
The main reason I bought the car was for transporting my road bike.
In terms of functionality, it performs admirably, the wagon bodystyle is very good at hauling around the road bike and makes Costco trips a breeze.
Performance - The engine power is adequate and the transmission shifts smoothly.
Fuel Economy - On the highway you can achieve near 30MPG with cruise control; however, city mileage is near not so pleasant, 12 or 14 MPG.
Handling/Ride Quality - Handling is okay and ride quality was a bit floaty.
I bought this Mercedes used. It has a moonroof, leather, 12 power seats, heated seats, all one touch windows, and shiftronic. It does everything right. Its been on one long trip so far and has excellent comfort and features. I love the car and plan to keep it for many years to come
Its in the shop as we speak. $650 sparkplug wire. If its electrical it is broken or has been repaired in the past. Lighted interior mirrors are $300. Over a $1,000 quoted to fix exterior temp reading LCD. I am 51 years old and owned many cars in my life, but this one has been towed and in for repair more than all the others combined. My other 3 vehicles are Toyota products. I will be buying another one soon and fortunately will shed my Benz before I am handed a $4,000 bill for something unexpected. Just incredible. Benz-Chrysler wont last long producing such a low reliability auto. Fool me once shame on you...but you wont fool me twice.
Like others, we bought the car thinking we'd keep it for a long time. After 6 years and many, many trips to the dealer we are saying bye to the Benz. Thankfully, the warranty covered replacement of the entire dashboard assembly, brakes, phone, hatch and various other electrical issues. Unfortunately, post-warranty I was stuck with the bill for the struts, rotors, hatch (again) and a new $100 key! Like others, it's burning oil at a rapid pace. The car drives well, is very stable and eats up highway miles. Performance in the snow is fantastic - better than our Land Rover! Cargo/people hauling space is great.
This is my third benz but first of the 21st century. I stayed away after hearing about issues after the DM/Chrysler merge, but was convinced by my mechanic that the w210 chassis are well constructed and reliable vehicles. While I still own my classic MBs, this is a fine vehicle with modern amenities like powerful A/C, ventilated seats, side curtain airbags. Powerful V6, 4matic, stability and traction control make this an all weather warrior. Car is new to me so I will report back later on reliability.
