Hmm, he listed it as a private owner sale.
He also has a 2006 e350 for sale that he lists as as a dealer on ebay. Looks to be on a dealer lot. Maybe the E300 was his car? or took it on trade?

Here's his house for sale HOME FOR SALE BY OWNER Home
Looks like he's taking a $300K loss, not my cup of tea.
and a boat...
1001 Boats

also a Tahoe, grand cherokee I saw.

Car dealer who's numbers are down?
