RE: Changing Your own oil?
$100 isn't bad for this job given the cost of the materials since it's synthetic oil and the better filter (about $70 or so if you do it yourself).
Top or bottom is fine; however, if you drain it (1) be sure you don't only raise one end of the car as you'll trap oil in the drain pan, and (2) be sure to use a new gasket/crush washer on the drain plug.
Also, MBZs use fully synthetic oil, (this is where the dramatic expense comes in) if you go with Mobil1 be sure to get 0w40, not any of their other variants. It's the only vis range Mobil1 recognizes as meeting MBZ specs. As well be sure to get the fleece oil filter kit, not the paper kind (you want the kit, not just the filter, because the kit includes new o-rings).
You'll also need a dedicated filter wrench to fit the housing properly, I recommend the composite ones because the housing cover is composite. When you put it back on, it's 25 nm (about 18 ft/lbs), don't over-tighten it since it's composite.
And the slick tip? Once you've pulled out all the old oil (or drained it and replaced the plug), while you have the filter assembly out, pour in your new oil right down the filter hole. Much easier and cleaner than trying to use the oil fill cap.
Take care and enjoy that beautiful ride,
