I just joined the M-B Club of America, mainly out of curiosity. It's not likely they'll have a big event within 35 miles of my house! But they do have a glossy magazine you may have seen in the waiting room at your local dealer, it's called "The Star". They have an on-line index and I looked up what they had to say about our B-Class back in 2014. They had a nice 1-page write-up, and they used a photo of the B-Class as a background on the Table of Contents. Of course, nothing said about it since.
I have placed the article here: http://robroy.dyndns.info/Images/star-p12_sm.jpg

In case you're interested, membership is $55 a year and you get a nice sticker for your car. The magazine is actually quite an interesting mix of historical stuff, restoration and a little about the current crop of cars.
