Those are the previously posted photos of the cars going to -somewhere- (Frankfurt?) for showing in a week or two. Previously posted, what, now about 10 times!? If they were "prototypes" they would say that on the windshield, like the GIII they showed in Edmonton years ago.
I come from 10 years of BMW forums... same behavior. Why do people post things that are highly likely to have been posted several times. did the original poster really think that a large prius forum would not have seen this this late in the game? really have to wonder sometimes.
