Listings such as this always beg the question w/ me: does the seller know his product or not?
As you've pointed out in these threads Wirewrkr, some people see "bmw" & price at $1 million! There was a rusted, rotted clutch assembly listed for over one year, it may be still, that even had a visible water line. Now, even if you don't know anything at all about mechanicals, how can such an item not clearly be junk?!
Last week there was an item listed wherein the seller mentioned to ask about any other parts a buyer may want from a /7 he's breaking. So I sent an inquiry about the jugs.
The reply included zero information or pics just: " Yes I have them, how much are you willing to pay?"
That speaks volumes to me.
Opinions are like internet connections- everybody has one.
