Whoopsy:

Haha oh boy.

What about the lack of stripes on the last car?

PTS is apparently not available with the stripes (unless maybe you're a Piech or Porsche or Whoopsy family member???).  The four standard colours come with the stripes, which are actually painted on the hood, roof, and ducktail, while the sides are done with optional decals.  So the photo is correct.
