"Running with a warranty " always costs 3 times what a mystery engine without a warranty does.
You could go to the wrecking yard and find the "best looking engine" in a car that has major collision damage, "assumed running fine and only ended up in there because of a wreck"
One should ask in this case what a warranty would really do for you, warranty to be a running engine... or warranty of it breaks... or just something to get you to pay more ...you decide.
