Glad it worked out for you. I was going to try to stop by anyway to meet you as the shop is 5 minutes from my home and my office. Turns out that I HAD to come by to pick my son up.
I figure they have good incentive to take care of me. I own 3 older Mercedes and I have referred several people to them.
Enjoy your car. It looked like a nice one!
Perhaps I will see you there again (hopefully not too soon).
Keep in touch with this forum. I am thinking about trying to set up a DC Mercedes Diesel meet in the Spring.
