Congrats - nice lookin' ride 
Congrats! I ended up in the same situation canceling my ProS order and picking up a Glacier White that was available at my local dealer. I must say the 1st Edition white steering wheel looks great with the Lunar Gray seats.
I believe the white one you saw was delivered to a customer who had a pre-oreder. The one I ended up getting was a stock vehicle which was expected to arrive sometime in April but they received it unexpectedly early (VIN in the 19xxx range). It was my lucky day 😀.I saw your Glacier White FE the day I took delivery of my Dusk Blue.
