Come back and let us know if/when you get the invite to configure your M3! I'm curious to see if this is true as well.Most certainly.
I was told that - based on my TM3 reservation status - that I should i expect to receive an invitation to configure my 3 days after becoming and owner.
I am non-owner and preordered on 4/1 and am scheduled to take deliver of my MS on Wednesday.
I waited in line on 3/31 in socal to reserve the model 3 and still waiting for my configurator to open up. I have purchased a model x and scheduled for delivery this Sunday! I believe you must have already taken delivery before owner priority kicks in, configuring and ordering the Model S/X online is not enough.
Had my MS since Sunday, still no invite (although i didn't become an official 'owner' until some time on Monday)
