First of all, I would like to thank you for your service to our country.
I would go thorough this forum as a lot of people have posted various issues and make a list of my own. Things to look for (from my perspective is following)
1. Panel misalignments
2. Charge port misalignment
3. Panel gaps all around
4. Color issues
5. Check to make sure frunk closes easily
6. Check to make sure trunk opens and closes easily with push of a button
6. Make sure back
Seats are aligned.
7. Make sure rear seats folds properly with push of a button.
There are plenty of YouTube videos with pictures which people have posted. Go through each one of them and make your notes. (Like the one below which really goes through a lot of issues).
