 I have owned my new Mercedes-Benz now for 6 months and I can't wait to trade it.  I wanted to trade it the first week after I purchased it but I was encouraged to drive it more because I "was just probably not accustomed to driving a German-engineered car." I developed calluses on my hands because the steering is so tight.  The longer I keep the car the smaller the interior seems to get.  I don't get the benefit of the instrumentation technology and upgraded sound system because it is too complicated for me to use. Everything stains the upgraded leather interior.  I have already had the seating re-dyed. I hope this has been my first and last poor car purchase decision.
