I would think if you were selling something you would list a price, where it is located , shipping etc.
It's like you refuse to give details......
Well, you might think that, mightn't you?
Maybe I was finding out if anyone was interested, and would invite them to PM for details.
Maybe I know what I paid to get the engines here, but do not know what the price in the collector market looks like, so wanted to chat offline with a prospective buyer.
Maybe, having come to a good faith agreement with another party, I would have sold the engine even if I did not need to, because I said I would.
Meh. Guess we'll never know, because you convinced me early on. Thanks for that!
