Prize Patrol

So I get this card in the mail today that reads, in part:

You are an official prizewinner in our new Mercedes, BMW,
Porsche, or $40,000 cash promotion. We have been unable to contact you...

Now, granted, I always ignore notices telling me that I have won contests I never actually entered, but this scam would be a tad more compelling if the last three people who lived at this address didn't receive the exact same card on the exact same day.
