FYI, for those of you traveling at end of year. I was shocked that after waiting over a year, they would give my car to the next person if I was not available those 3 days. I am home, so it is fine for me.
Here is the communication..
“We are very excited for you! Just to be on the same page, the car is expected to arrive sometime around the 29th of December. This vehicle will need to be delivered in December. Is there a possibility that you won't be available on the 29-31? If you won't be then we will just have to wait for the next VIN because we are unable to hold the car into the new year.”
