The Prius limo gets around.

Also, the Prius in your photo is the body style that came after this body style.

And when you have a welder and metal fabrication tools, you can make any weird shit you want. Including that step-up window.

I’ve owned several Prius models and it looks fake to me. I can’t see where the middle door could come from.

The downward indented window does not exist.

Look at that wobbly roofline too.

What you're mentioning is actually the very thing that makes this photo credible.

Notice how in the original Prius the bottom window line is sloping downward, it's not parallel to the ground.

To squeeze a door between the other two and not break the design by leading the line in an odd angle, they had to introduce that ramp in the middle.

Apparently this very vehicle does in fact exist. Or if it doesn't, the idea has been stolen by several others and reused verbatim, including the wonky middle doors.

In the EU, if some abomination like that enters the peripheral vision of a police officer, prepare your car to be impounded and ground to dust a week later.
