I just had to say something about this, I see all kinds of Mercedes cars with wheels from who knows where. I would think that the wheel on a mercedes is engineered specifically for that car and therefore the the best wheel for that car. I would never drive a Mercedes very fast with some other kind of wheels on it. Some people are more interested in bling bling and getting attention than they are with safety and engineering. Keep the car the way it was designed. Mercedes Engineers have been doing this longer than I have been alive and I believe the wheels they put on my car are probably better than something I can pick up at a local tire shop.
Those shiny wheels are nice, those bigs wheels get attention, but I would rather have peace of mind that I am not causing undue stress on my suspension components and a potential hazard of a wheel flying off, I also have comfort in the fact that I would rather have money in the bank than pay to replace something that works perfectly fine already.
Keep the car a Mercedes!
Happy Benzing,
