Sure it does.
Caveat Emptor applies anytime anyone is considering buying anything. More so with used vehicles and most so with imported grey market vehicles.
A major portion of the allure with Defenders is that they are scarce and/or forbidden in the US, and with that can come lack of traceability. Our legal system is full of cases where consumers didn't apply sufficient caveat emptor with a purchase and now looking for legal recourse; at tax payers expense. People are duped hourly in our country. I'm not saying that that applies to this situation, but, in general, I feel people need to add more skepticism to their business transaction.
As Adam noted in the coming days the legal driver for this situation may put the feds in very different light. But that doesn't reduce the risk of ROW Defender ownership in the US.
