It's hard to even find a good example that isn't marked up or pre-sold so I get the anxiety. I spent 3 months finding my car.
You'll be fine though, hopefully this will be useful for other people in the same situation because I was googling it and didn't find much then either.
I had this happen a month ago and thought the same thing. After a few days sales rep called me to let me know the car was being delivered. Bought it a couple days later.
If it makes you feel better here's the text messages. 5 Days later the car was delivered.
