I got a letter about a month and a half after buying the car telling me that as a purchaser of an ST car I can go to the academy and information on the website and so on. It was obvious that whoever sent ti out didn't cross reference their mailing list against people who had already registered, because I had already done so.
It might have been a new thing because it talked about both the academy for Fiesta/Focus in North Carolina and the Explorer/Escape in Utah.
