After reading some review Ive decided to write my own. In 2008 I bought for my spouse an R350 4Matic.
We drove it and took it on trips all the time and never gave us any trouble (except a few blown lights) and eventually put close to 40k miles on it.
On June 2010 my wife was driving in the city with both our kids when an elderly lady wich had a suspended licence drove right into her lane (she crashed head on). When I arrived I saw the car totalled but my wife and kids with out a scratch on. The car's crash alert system had been activated (it moved the drivers seat all the way forward, it moved the steering wheel, cut the engine and even placed the hazards lights on).
My dad always told me that a car is just a car that takes you from point A to point B. But on this day I realized why we crazy MB owners pay what we pay, safety and peace of mind. So here I am about to purchase my 2nd R-Class.
