I got my 2018 E300 4Matic last June with 37,000 miles. I took it in at just under 50,000 miles for what I thought was "Service A" -- and that's what the dealer told me. I was told to bring the car back at 60,000 miles for what they told me was "Service B" and that I should replace the spark plugs (which they recommend at 60,000 miles). Last week I hit 55,000 miles and the warning light is saying that the Service A is over by 100 miles. Then 200 miles, then 300, and now 500.

So, question 1 -- what service do I need/want to get now or at 60,000 miles?
Question 2 -- where should I get it done? The dealer is not running any specials. Some people have recommended Wolfgang's, but when I call, they aren't really clear on what service I need, and more importantly, they aren't very clear on what's included in Service B, and even more importantly, they are not very keen on giving price quotes. That doesn't make sense to me. Service B should include A, B, C, and D, etc., and there should be a price for it. The dealer can do this. I get that Wolfgang's doesn't like it, OK, that's their business, MO, etc.

Any other recommendations on indy shops in the Northern NJ area (Bergen County, nearby)? Thank you very much in advance.

You can go to an indy shop unless your car is CPO and under warranty,etc.

Thanks! Bells is actually on the way home from my office. I sometimes wondered about it when I passed it, but I've never seen the name thrown around. I'll give a call over there.
Thank you also for the required services list! I greatly appreciate it!

FWIW, the MB service booklet gives the choice of miles or years in service. I am driving my car - 2011 E350 4MATiC - less than 10K/year so have been following the years in service guidelines.

My car is under warranty/CPO -- but the service work I am having done now is not covered under warranty. It's strictly service. Thanks.

Good point. Thanks. I tend to use the car 8 to 9 months a year, almost daily. I garage it for the winter. Given my usage, I have to maintain the service schedule via mileage, not time. Thanks again.

Bells is excellent-
