Best scam I've ever seen

The fact that the letter says "You may have been selected to receive this special limited time offer because of [...] This is an advertisement to extend your coverage." didn't give it away?

Where are the scammers getting the data indicating the resident listed at this address drives a Toyota Camry? Obviously they don't have the data linking the car make to the owner, or else the mail would be addressed to the fiancé of the author rather than the author himself. I wonder if they are using a simple Name:Address mapping (certainly not hard to obtain) and then indexing the color and make of the cars with Google maps.

Clearly the data for name/address pairs and car/address pairs come from different sources. Otherwise there would be no false positives like the author's letter.

(Also, why don't they just use a different phone number for each letter? Or even sets of 3 letters?)

Legitimate business correspondence generally doesn't have threatening language on the envelope quoting penalties under 18 USC for "obstructing with delivery of this letter". Something like that would end up in my recycling bin without even getting opened.

I've received a few of these in the mail, but the fact that they were clearly from a third party made me trash them immediately. It's interesting to hear that they don't even provide the extended warranty they are advertising.
