Vehicle No 1 of 13 !!
Motor Show vehicle of Geneva 2018
Never admitted.

This McLaren of the Ultimate Series is the first of a maximum of 13 previous prototypes (XP = experimental) that were factory rebuilt after the production of the standard Senna models and were available to order for selected McLaren customers. This particular vehicle bears the serial number 1 of the XP. It is obviously the exhibition vehicle that was exhibited at the Geneva Motor Show in 2018 at the world premiere of the Senna.
