I can confirm after speaking to the disgraced STIG, some say he was fired after humping Jeremy's leg when Hammond no longer had the "scent", that this was included as part of the TOP GEAR deal but Ferrari would not allow it to compete with their cars.
Their argument is, it competes on an unrivalled scale of performance and aesthetics. They were not willing to compete against a no budget no regulation manufacturer as it offered unfair competition.
