Well, that is something to start with. Car P is indeed an Amilcar Type M and Extra y is Isadora Duncan (who lost her life in an Amilcar, the scarf, you know). What's missing is the Architecture part, i.e. one of those pictures captioned Carchitextra Architecture 1 to 26. But, since you've got two out of three right, I place a lock for you on that combination P-?-y.
