Good for you. You will like it. If you ever get where you want to read codes and such pick up a good, used Autel MaxiDas and you will have all the communication equipment you will need on it. MaKe sure it is MB compatible.

I maintain my cousins 2010 E class wagon and it is a good car that is, for the most part, easy to work on if you have the right tools.
