Earlier quoted context omitted.
While being not even the biggest in total number of sales (wikipedia says fifth). I still find it strange that it's a Dutch company (and Fiat Chrystler before it), since the Netherlands has no local-origin car manufacturer since DAF-Cars was sold to Volvo in the '70.
The reason for being a Dutch company is purely for a taxation advantage, and it goes back to the fact that FIAT/FCA moved its headquarters to the Netherlands under Marchionne's leadership. Other italian companies (Mediaset owned by Berlusconi Family) did this too recently: ( https://www.ilfattoquotidiano.it/2021/09/18/mediaset-la-sede... )
no it was not taxation but legal reasons. as it takes years in italy to get a decision from judges.
