I would want to see it running before I purchased it otherwise I would want a huge discount to compensate for assuming the risk that it might not work or needs expensive parts
to make it right. It's a crap shoot without a warranty from the person selling the engine.
If I just wanted an engine that I know is going to work, I would not purchase
it. If I was trying to save a lot of money
and am willing to take some risk then I might purchase
I think it would be unwise to purchase an unknown without a big discount or a warranty.
It depends on where you are with this.
are super expensive if anything needs replacing. This is how Volvo makes its money
, selling competitively prices engines and then later price
gouging you on the parts.
