I assumed the red car shown yesterday was the same one we saw on stage on 3/31, but there are a couple minor design differences I noticed between the one we saw yesterday and the ones we've seen before now. First, the side mirrors are definitely angled down on the one at the gigafactory. Look at any of the pictures and you notice it right away. It's almost odd, but it does follow the curve that flows from the headlight to the A pillar. Second, there is an obvious crease present below the headlights in all of the prototypes we've seen so far. This is not present on the gigafactory car. The other creases seem more subtle/rounded as well, but that COULD be lighting. The one below the doors stands out to me. Look right in front of the back wheel in both pictures.
