If you are the owner of a Mercedes-Benz….CONGRATULATIONS! You are the owner of a superb piece of German engineering, and a worldwide symbol of luxury.
You are also the owner of one of the heaviest passenger cars on the market. Hey, all of that safety and stout craftsmanship is the product of using solid materials, and those solid materials are heavy. Cheap plastic is lightweight; expensive metals are heavy.
What are we leading up to? The heavier the vehicle, the more stress is put on the braking system, and that means you will be paying for brake maintenance more often with a Mercedes than you would with, say, a Toyota or Honda.
