After much confusion from Mercedes on my ECU update, I finally made the 4-hour drive to the dealer for the update. While at the dealership I had hoped to have the tires rotated, alignment done, fluids checked, oil changed and anything else that needed to be done. After waiting 4.5 hours I assumed everything was going well and the items were being serviced. Finally the vehicle was done and much to my surprise the only items completed was the ECU update which was supposed to take less than an hour. I waited half the day for this? And now have to drive 4 hours in the dark through the mountains and find someone else to do the tire rotation and alignment. Highly disappointed and didn't even get a car wash out of the deal.
