I had some issues with mine. I was not satisfied with how it looked, so I had Rivian send it out to a body shop for repairs (under warranty). They are still working on it, but progress is being made!
If you are moving with your own personal vehicle, and not importing it with the intention to resell, Rivian will be helpful with all that you need to be compliant. it's a different conversation when you're importing to turn a profit.
I was assigned VIN/8 Steps March 1st. completed 7 steps, and heard nothing with regards to ETA. March 25th I got a text to schedule delivery. Picked up my truck March 29th.
