I finally snagged a set of W124 chassis body manuals from ebay last night for $73. I had been checking ebay regularly, searching under "mercedes chassis". This item was just listed as "mercedes repair manuals" so it may have escaped the attention and bidding that the chassis manuals usually bring. I bought a M104 engine manual from a fellow list member for $60. The last serveral auctions I have seen for both new or used manuals always end up around $60 each.
