I've received a variation of this number several times. The number comes up, but no name, so I do not pick up, and they did not let a message. Car warranty sounds right. I keep getting mail from what looks like a legitimate business telling me my car warranty is up and I should call to renew extended coverage. My dealer told me not to respond, that he's gotten others asking about it, too
It is a telemarketer regarding some kind of protection for your car, I think it is a scam I called the number back and got the name Jeff and asked him to put me on his do not call list, he new what kind of car i used to drive.
