Thanks for the update, like you I have a black roadster but unlike you I came to the party much more recently. I purchased mine February of 2013 with 36,000 miles, so far it has performed flawlessly and like you I love it. I have an independent garage that I trust with my vehicles that claims to work on any make or model and I have seen several MB on their lot so hopefully they will be able to handle any problem that may pop up. Now that you are back stick around become more active, your ownership insight can only help other going forward.
