Yes unfortunately. I order + on day one. Changed my mind a couple weeks later. Originally I was told they could just change my reservation without losing my place in line. Yay! Then, a couple days later, they reached out and said that was a mistake and that they couldn’t just change my reservation to a Plaid. They canceled my reservation, refunded my money and told me to reserve a new car with deposit, which you can imagine sent me to the back of the line. This was like 3-4 weeks ago. My date is in the 4-11 week camp.
Pretty frustrating that you can’t just change the model. If you have any different luck, please report back. Maybe things are different now that they moved the date so far out.
