Wow, 8TL isn't on my build sheet - sounds like that could very well be LED corona rings! This would be the first word that they are updating the corona rings with this mid-year refresh.
Bummer for the rest of us who missed out, but exciting for you.
And don't worry about the website tracking - it's always off, as long as your Dealerspeed printout is correct, everything will be made correctly.
