Dealer friend has an ML 350 08, decribed as Mercedes Sport ,1500 miles coming in in trade, they dont like it (silly consumer), 3rd row seat, navigation, grey silver, that is all I know. What's it worth? What do you need to know in terms of packages? Is it likely over 50 new? I can get for low 40's.

I looked at these a year or so ago, and I knew that you needed to buy an upgraded package to get the third row. However, in perusing Mercedes site, saw no reference to 3rd row as an option. Might it be standard on the 08's? If so, maybe not as special of a deal. I wasn't in the market, but I perceive this to be a very good price.

HELP!
