That's all of them from the F40 to the LaFerrari, if that wasn't clear.
Ferrari's really top-end hypercars have been few and far between. This is done intentionally, and it's certainly worth the wait for something as amazing as any one of these cars. There are all obviously fairly jaw-dropping on their own, but the rare site of all four together in one place and all in the same color is a very rare treat. We unfortunately don't know the story here, and whether these all belong to the same person or not.
We suppose it's possible that this was just an unbelievable coincidence, stranger things have happened, but that would be quite impressive.
