4:17 - the two robotic arms are used to install the piston rings. Because they have to shrink them down to fit inside the crevice, the rings have to be dipped in liquid nitrogen, which is very dangerous. That's why robots are used. I find it cute that they name the robots Romeo and Juliet. Romeo dips the ring in the liquid n2 and Juliet "accepts" it for installation.
Ferrari don't have problems like they used to back in the 80s. All super cars from the 80s and 90s were sketchy. What you think of "problems" now are really maintenance cost. There is no super car out there today that does not cost money to maintain do to complexity. Maybe the GMA t.50 is the easiest of them all.
