I was told the same thing at a local MBCA event a couple months ago. The complete 2017 MY diesel lineup has been scrubbed from the US.

What is funny is I keep getting postcards and e-mails from the dealer telling me to trade up to a GLE diesel. It's a 2016 model that costs $56k. No thanks, I just got done fixing the oil cooler seals on my 2008 and it's almost paid off...
