Purchase Advice
The current vehicle I am looking at is a 2011 E350 with around 30-40k miles. I have a few weeks to decide as I will be buying the car when I go to Dallas since the prices are usually around $2000-$3000 cheaper there compared to here in Phoenix. The problem I am currently trying to solve is whether to choose the E350 Luxury or the E350 4MATIC. My current fleet is all hybrid so this is new territory for me as far as the business aspect is concerned. Generally my vehicles are driving between 70,000-100,000 miles per year with multiple drivers. The E350 choice I make will be driven by me alone so those numbers will be cut in half probably.
My question is when I get a car for the purpose of heavy mileage use, which of the 2 cars would be better suited for this use and what are the pitfalls I should be aware of before I go and purchase one or the other. What are the differences and what are the common mechanical problems that arise with both cars? Luxury or 4MATIC, which would you go for in my position.




There are those who proslytise about the other "advantages" of 4MATIC, but basically it is just a 4 wheel drive vehicle, which is good for snow.




Go drive one before you jump.

Up here in the great white north MB Canada does not use this terminology as they offer many packages and pic and play stuff when ordering a car.
Would you be kind enough to explain the nomenclature of P1 and P2 for me?
Thanks.

The lack of diesel availability is one of the many 'truths' that Toyota has been using in their most recent deceptive advertising for the Prius, e.g. full page advertisement in National Geographic Magazine. It's a load of horse sh_t !! Diesel is widely available throughout North America !!!
But even more important is the fact that Mercedes-Benz builds the best diesels on the planet. Their diesel cars have reliable, powerful, torque-rich and fuel efficient engines !

It also is that the modern diesel engines give so good mileage that if you for some reason would find a station without the correct diesel you can get to the next one unless you drive it dry before the first one.
These diesels also make your fuel 35-40% cheaper. For a gallon it is roughly the same as the premium our gasoline engines burn but the fuel mileage easily is 40% better. And comparing the performance to the E350 it is stronger from the line.
What comes to diesels in Germany, it is the whole Europe. Diesels have been developed to the top there and has been the main choice of engine for tens of years already. And yes, GM, Ford and Chrysler all have very nice diesel powered cars in European roads, have had for a long time. They just choose not to sell them here in the North American market, but they will be.
It now has 74k miles and has been mechanically flawless. 6 Cylinder Mercedes have plenty of power for me and less expensive to maintain.








Gasoline engine gives you say 25 MPG and the diesel 40 MPG. These are very realistic numbers on highway driving.
With the gasoline engine fuel cost is $3.1 / 25 = $0.124/mile.
With the diesel engine fuel cost is $3.50 / 40 = $0.0875 / mile.
This means gasoline engine car fuel cost is 41.7% more expensive than the diesel while the fuel is $0.40 cheaper for a gallon.
In above I used 40 MPG for the E350 BlueTec but I think I have seen posts from people driving these with a lot higher MPG numbers.
For the gasoline E350 I know as I had one and the best I got was at around 27 MPG but this was on a trip when I really babied it and drove slower than normal. On highway it normally gave 24 - 25 MPG.





I had an E320 CDI for over 8 years it was a great car. I got an E550 to replace it, no way I was going for the new E250 4 cylinder, although I wasn't going for a gas E350 either. This is the first time in 15 years I have't had a diesel car. When ULSD mandate hit the BTU energy in the fuel went down (instead of cost increasing) as did my MPG combine that with the higher cost relative to gas currently, and my 1.3 mile commute and I went for a V8. If I were the OP I would consider an E350BT.
