National Theft and Recovery Letter - Scam?

I just received a letter from NTSR it said Anti-Theft Tracking Expiration Notice . It also said Registration is Required for your vehicle to received this service. We are waiving 399.00 fee the police traceable Decals cost when you register. Did the quick google thing and I see lots of complaints, but it also seems that most of the people who were complaining thought it was free. While they do mention that this costs about $143 and $20 per year, it still has that smell of not being really legit. Just figured I would post on the forum in case someone has ever had a stolen car recovered by this outfit. I am going to start holding my breath right now, so I really hope someone has some good experiences with these folks....

 

Scam.
