Well here's my 2 cents.
I was one of the very first to place my order, early on (East Coast) Tuesday November 27th, 2018. Back then, I did not have to specify which model I wanted, the R1T or the R1S. I was also told the price would be around $60,000. That soon became "$60,000 Before government rebate of $7,500". So supposedly $67,500 which Rivian conveniently rounded to $69,000.
Production schedule was the same for both R1T and R1S, end of 2019.
After months of hearing nothing from Rivian, they finally said production will start early 2020, which soon became late 2020. Then it was to be early 2021. Then the Corona virus hit and Rivian conveniently used it as an excuse to push production out to June 2021. So a lot of promises so far.
I have been asking for color choices and options for over a year now and I am still sure when we can specify what we want.
Meanwhile, not happy with all the delays, I ordered me a Performance Tesla Y, requiring a $2000 deposit. (Nov 13th, 2019)) I am still waiting on it as well.
Then I saw the Cybertruck and thought it was a joke! It has since grown on me and for a $100 deposit, I thought why not. So I also have a Cybertruck on order, thinking it might get here before the Rivian.
I currently drive a fast (400hp) 2018 Audi S3 and my wife drives a 2018 SQ5. When I get my Tesla my kid will get the S3 and I'll drive the Tesla.
I am a close follower of all electric vehicles out there and could not resist to place an order for a Tesla Semi truck in Jan 2020! Yikes, a $20,000 deposit for that one. Hoping to be one of the first.
So I was in doubt as to whether I should keep my Rivian order. That has changed now and I cannot wait for it. June/July 2021 works out great for me, I will sell the Audi, give my Tesla to the wife will be happy with my Rivian. A short while after my order I mentioned that I prefer the SUV but really will take whichever one I can get first. I think they've assigned me the R1S, SUV.
Hopefully I will still be given the option between the two.
