If you want to tow a trailer with your Fiat 500 or use hitch mount accessories like a rear bicycle carrier you need a proper trailer hitch. 

CURT® - Class 3 Black Trailer Hitch with Receiver Opening is one of the most popular models and we have it available for the 2016 Fiat 500X: http://www.carid.com/2016-fiat-500x-trailer-hitches/curt-rear-trailer-hitches-81524255.html

I am quite surprised that the tow bar hitch will fit the Fiat 500 / Abarth 500.

In 2014 I bought part no #11347 from a Curt approved retailer in the States. When it came to fitting at an multi-brand approved fitter, they said the mounting holes were reversed.

I still have the hitch at home in the garage gathering dust. I can send you photos if you like to vertify whether it is identical to that shown on the website.
