Congrats on the new E!!! I'm glad to see a youth buy an E.
Also, to answer your questions: AT is Automatic Trans ans MT is Manual Trans. Looks like Alabaster Silver Mettalic, your best bet is to call a Honda dealer and have them run the VIN.
Or use the Vin decoder on this sight!
But for color code, Ramblerdan comes through in spades! It's easy, take a look!
