That's marketing! Mercedes Benz do that on purpose selling only 20 cars a year! Now, we all know people have to be put on wait list because of the small number production. MB and AMG can work that out but they won't do that.
I've seen the actual car in the dealership.... since it's a baby class of the line, the material and make is not as sturdy as the regular C or E class.... it feels like a well make Honda or Toyota... the turbo engine definitely will burn engine oil like crazy.... would be better to wait for the new C.
