Does anyone know anything about the prices of the cars, new or used? I mean, I was talking to a salesman who said the price on the sticker is the price you get because they are standardizing all the pricing schemes so it does not pay to shop around. I suppose that used cars are not controlled in this case because it is subjective but what about say a new M class? Would I benifit by going say up to 500 miles away or is the salesman telling the truth? TIA.
