Hey, MAN, whatever rock your boat
I've been repainting MB original caps for previous decade, only to discover that just for few bucks I can have chromed version for less.
Once again, per my limited experience - the Chinese caps hold better than OEM Mercedes.
Than heck, for $10 or 20 I can change them every year.
It is amazing how small things can go unnoticed on big scale, but make an impression on back of your head.
Just recently I had local forum member driving by my car and even it is just plain wagon, he was so occupy watching my Lorinser monoblocks, that he did notice me waving to him for almost a minute.
