Bought mine at Jerry's in Weatherford. Significantly better price than the competition for the Premium 2 trim, and getting my preferred interior (chestnut) was a bonus.
Service was quick and friendly when I requested they check for "your" TSB, when I also discovered my build date was 08/16.
Waiting to see what happens today when I return for the "Waiting for media update" head unit shutdown issue to be addressed.
Now that service end feedback of your sound really good to me since in the past Buick hasn't been know for customer service, instead falling into what everyone typically thinks about GM customer service.
Hey maybe they're taking note from Toyota/Lexus
