What "bias"? I'm not Argentinian, I couldn't care less if they made it or not.
There's clear differences even in the photos you provided. Obviously the front grill, but the lights are also a different shape, with the TITO more angular. The door frame is different, it looks like the TITO has a larger piece of chrome on the part you open. I'm sure there's other differences there if I were to look at different angles of the TITO.
Maybe Sunshine took TITO's design, maybe they're both based on some reference design made by some other company. They both clearly are supposed to be a squished MINI Cooper. Regardless of what happened, "my eyes" are not proof of it.
So, I ask again, what proof do you have that it is the case that TITO took Sunshine's design and/or is just a rebadged car?
