I talked to someone in the automotive business to take a look at the following video.
I am not sure how to explain in English but this person is in the car lining business (everything inside the car : mats, coating, foam, acoustics,...)
I know the following are details and the car in the video is a beta, still it was very interesting to hear the comment.
In the video at minute 3:36 you can see the inside where the door closes. The space between the white and the grey part in the jamb is to big. Both parts should connect better.
Minute 3:57, the frunk. There are three different colors for the materials of the frunk. The part above the little net is light grey. The left and right side is a little darker. The bottom is even more dark. This means they used three different materials.
Minute 6:09 . Same remark, the left and right material is different from the material used for the bottom. Also notice how the rear seats don't connect correctly where there is a bend. Furthermore the rectangle shaped covers on the bottom of the seat are not equally high. The right one, of the smaller seat, is higher than the left one.
These comments are all details, and given on what we could see on a video. I found them very interesting, since I have no knowledge of these kind of details.
Besides these comments the person thought is was a very nice and cool car.
