Great advice from CJ and Peter. I learned my lesson well years ago, when I purchased a Conti 2grp, and an older Faema 2grp. Both had ruptured heat exchangers
in the boilers(stored with water in them,water froze, hence, I was looking at scrap or parting out parts. Yes, you could purchase new boilers(quoted $600-$800.00).I paid $480 for both machines. Decided against the new boilers. I would recommend seeing the machine plugged in, plumbed in, and operational before shelling out the coin. Cleaning, small leaks from gaskets and washers most often are easy fixes. I noticed in your pic, the left knob for steam wand is missing. Does he have theportafilters for the machine? Finding them could be another bottle of aspirin(if you could find them!). Be cautious on this considered purchase.
