That would be one way of looking at it. I am certainly balancing the risk of loosing $250 against the possible gain of a great deal on a really nice saw.
Except that isn't my claim. I was motivated to buy it because I wanted a good deal on a saw, and then I discovered that it was almost certainly stolen. I boldly confronted the seller, struck the price down to a "certainly hot" price, and then I did my damnedest to catch them for prosecution.
Failing at that enterprise, I did what I thought was my best to recover the situation. Having negotiated a price for the saw, I either had to put up the money, or watch the thieves walk away with it.
Many would have kept the deal and kept the saw, reporting nothing. This would be a complete lack of moral integrity.
Some would have taken the smooth, easy, high ground and sent them packing. That will give you a sense of being honorable, but does nothing to stop thieving, and it certainly doesn't help catch them. It is the easy way out. No risk, no corruption of morals, no satisfaction for correcting a wrong. As a confession on my part, no chance of coming up with a good saw, either.
I chose the very rocky middle ground. I paid hard cash for the saw, reported it to the proper authority at risk of my loss, and I am at much further risk of involving myself with prosecution of the bad guys and potential retaliation.
I will certainly confess that I was tempted by the value of the saw. Quite frankly, I don't care about the engine, since I have lots of other saws bigger than that. I was genuinely interested in the 36" bar, since I have a 660 without one, and I recently attempted to buy a 36" bar for it. And I also probably have a mild case of CAD, also.
BTW: isn't a 36" bar a little big for a MS-460?
