Yes, Italy and Spain are the main markets for the Minauto as far as I know. Minauto surely is a part of Aixam-Méga, but a brand of its own. As you can see, it doesn't have the Aixam logo at the grille, but an M for Minauto.
I guess it is an attempt to create a low-price microcar without fearing that the "cheap and primitive" image touches the Aixam marque. Similar things happen with the new Dué brand, being a low-price Microcar.
A well-earned point goes to you.
