hi all,
my friends' parents were looking to buy japanese sedan and willing to spend up to $30k. i suggested that they consider an 06/07 E350 that's CPO'd w/ 7yrs/100k miles warranty. if they're looking for one w/ max of 35k, what do you think the going price might be? it appears that used MB prices have rebounded a bit since nov/dec 2008?
