So far zero problems with this car. I bought it transferred from Houston to Phoenix with 45k mi, and have 60k mi now. Everything is perfect. Fuel mileage summer 24/36 winter 29/38 city/highway. My typical city driving is 6 mile each way with 15 lights. hwy hilly and 75 to 80mph. Note ac use is the mpg killer in Phoenix.
This car's average mileage for its first 51,000 miles is 30,6. On the highway I get 41+ at 70 mph. Add Mercedes legendary comfort and handling and this is a great car. I bought it used in 2009 from a dealer with a full MB warranty for $28 k. I'll never buy a new one again! It is my fourth Benz/first diesel, and I am now a diesel convert. Why drive anything else?
I bought this car as a used car at a dealership. Got an excellent price. Has over 126k miles but drives like new. Everything works like new. The interior is in pristine condition. For people who spill the occasional drink the stainguard on the floor mat works marvelously.
The gas mileage is averaging 35 mph with a/c in Phoenix at speeds averaging 70 mph. I read previously an issue with that but I haven't experienced it. I drive 80 roundtrip miles daily and this car is perfect for it. My carpool buddy loves how comfortable the seats can be for his naps on the way home. The overhead lighting for the back seat passengers is very helpful for passengers to navigate maps, etc while I'm driving.
I bought this CPO car sight unseen from a dealer about 800 miles from home. I flew there, picked up the car, and drove it home. The car was virtually flawless. I was a little worried when the CEL came on the second day, but the selling dealer said not to worry...get it checked when I got home. I did...and it turned out to be a bad glow plug. My local dealer replaced all six plugs per a TSB. I have owned several Mercedes diesels in the past but this one blows the others out of the water. It has very strong acceleration! How great is that in a diesel (remember the ones from the 80s?)! I got slightly better than 40 mpg on my drive home and in combination city/freeway get 30+. Great car
Finally, after 30 years of dreaming of buying a Mercedes Diesel, I finally have one. I purchased a used 2006 E320 CDI in November of 2009. I am beyond impressed. First, the vehicles systems are easy to access, air, fuel and air filters all are easy to access and change. I am a bit of a technical nut so this is important and it should be important to every person as it makes repairs cheaper. This car is built like a panzer tank. It effortlessly cruises at 100 and the economy is uncanny. I routinely get 40 MPG in MIXED DRIVING. My best is 45 MPG on a trip on Maine. This car is Quiet, and remarkable powerful. It blows away my BMW 3 series. LOVE IT LOVE IT LOVE IT!!
