Just wrapped this for my parents:
Model: 2017 E300 4Matic P1
Miles: 6k
MSRP: $61,795
Sale Price: $50k
Terms: 36months /10k miles
Acquisition fee: $1,095 (I let the mark up go)
Doc Fee: $499
10 MSD: $4,500
Tax: 7.35% or something in that range
Total out of pocket: $6,859
Original quote was $560 a month, I offered $400 and my father was so embarrassed at what he thought was my silly counter that he tried to make me email him to disregard it (otherwise he would think we weren’t serious). Happily, they came back with the deal above, though I know I could have squeezed further given @Irving 's great deal but my dad was happy so I left it alone and got floor mats thrown in.

Edit: Turns out the dealer over charged on taxes so the price has dropped from $399, now with maintenance included.
