Ah, no. Those clear carts would look like absolute shit if you painted them, and they wouldn't fool a retarded kid. Also, you didn't address the sticker on the back either.
In order to have the correct color and proper looking back label, it take a lot more than spray painting some crappy cart. If you've ever seen one in person, you'd know it wouldn't be that easy to reproduce, nor would it be cost effective.
So are you asking because you're afraid of getting fooled by some POS spay painted cart? Are you hoping to reproduce one yourself? Or are you just arguing for the sake of arguing? Whatever the reason, I don't see the rationing behind it.
To answer initial question again: Yellow cart, sticker with no stamp.
