Ar first glance the letter looks legitimate with a logo and title:VEHICLE SERVICE DEPARTMENT
VEHICLE DOCUMENT ALERT NOTICE
PERSONAL & CONFIDENTIAL accompanied by the "EXAMPLE REPAIR INVOICE ENCLOSED" (it even looked like it could have been sent by the NY state department of motor vehicles!)
However, I have used the same service for every Subaru I have owned for more than 25 years, so it was obvious to me that while the "Notice" appeared legitimate, it was not.
