In my case, I told the dealerships I was okay with waiting up to two years to get the exact trim I wanted. I told them whichever dealership could get me an allocation first got the sale. Then I literally stood up to leave.
And like magic, they went to the computer and found the exact trim I wanted and got my allocation a month out. I was extremely picky on color and options, though. If I had been flexible on color it would have been sooner.
The sales people at dealerships will pressure you into upsells. They’re not going to turn down an easy sale if you demonstrate that you know what you’re doing. They were trying to upsell you.
