I did the exact thing, ordered mine July 18 in carbonized grey, then two says ago I changed it to Terrain and added the co. Pilot 360, next day I got the email for it to be built Oct 23 as well. Weird
Im not sure who's the leader is but my VIN is showing A00XXX, orderd 9/17 and it's not a rollover. XLT, Lux.... Luckily yesterday I changed my color to Terrain and added Co pilot 360. Got lucky for the timing.
