Of course, if he doesn't already realize this, then he has bigger problems.
To be fair, we’re pretty sure that the owner of this “replica”, one Benedetto Bufalino, wasn’t thinking that anyone would actually believe that he had a Testarossa, and that the cardboard Ferrari was just made because he thought it was funny. At least, we sincerely hope that was his thinking. Cardboard, foil, paint and what we assume is a huge quantity of duct tape went into the building of this model, and apparently Mr. Bufalino drives around with it on regularly.
In fact, we have a video of him doing just that, and it looks exactly as ridiculous as you would think it would.
