I just noticed something that I don't remember reading about in the owners manual. When I unlock my door with the remote and don't open the door right away, in about 30 seconds it re-locks itself. Is this a safety feature, or is something screwy?
The Mercedes had two service intervals, A and B, and they alternated every 10,000 miles. Service A was about $275 and service B was about $400. What did they do? No idea. As owners we weren't expected to know or care about what they did to the cars during service. We were only expected to pay for the service and feel good about it.
I never felt good about it. I work with auto dealers on a regular basis, and a BMW dealer we work with mentioned that his customers are angry, literally angry, if their bill for service is less than $500. Wow. No thanks. The Mercedes was a fantastic vehicle with exceptional attention to detail, but the ownership cost was absurd. Not at all worth it.
