I'm sure the seller was confused, but don't know since he has not gotten back to me. I emailed, called and left a text, then a second text. It was posted Oct 25th- how the hell it escaped my CL searches is beyond me. I commonly search "mercedes diesel" and many other terms used which denote that.

I think the seller is the son, and the 81K vs 89K is a non issue as others wondered about. I sounds like it's a Palm Beacher estate sale by the son.
