Not sure if it is a scam or not, but they are pushy, rude, and attempt to make you believe you must do what they say.  When I asked for more details the man on the line informed me that it was to continue my current bumper to bumper 100k mile warranty for my Toyata... Which I have never owned.  When I explained I didn't have one they hung up.

THIS IS A SCAM.   I received this call from a dialer on Sunday at 8:44 a.m. CST which is 6:44 PST.    When I blocked my number and called got the following:You have reached the corporate offices of the National Auto Division.  Since you are calling outside of  our normal operating hours of Monday through Friday from 9a.m. to 5 p.m. EST the offices are closed.  To levae a message to speak to a representative about special offers of covergage that may be available on your current vehicle, please press 1.  To opt out of being contacted about coverage available on your CURRENT AND/OR FUTURE VECHILES PLEASE PRESS 2.  THIS IS A SCAM.  I WAS ASLEEP AND DID NOT LOOK AT MY CALLER I.D. BEFORE I ANSWERED.

The individual calling from this number does not speak and then disconnects. This individual calls every day.

I get a call every day from National Auto Warranty Seattle, WA andt hey will not remove my # from there call list. I have asked several times and all that does is make them call even more!! The lady just kept reading her speach. Does anyone really buy from these morons!! How do you get rid of this crap!!!

They call me everyone morning. They want $2700 for their warranty. They keep calling even though I told them not interested. The second guy said its a "fresh list."  It only just started last week. So it's been about 8 times.
