Travelling to Amalfi coast. Is it safe going by car? [closed]

My girlfriend and I are planning a short trip to visit Amalfi coast and Naples.

We planned to arrive in Salerno and spend two days visiting the cities and the beaches of Amalfi coast (swimming etc). Then, on the third day move to Naples and visit the city.

I am a little bit concerned to go there by car since a few friends advised me against due to stealing and damaging potential.

I would like to know if there are safe parkings along this itinerary (I guess we can find an hotel with guarded parking in Salerno and leave the car there for the first two nights);

• Is it safe enough during the day to park the car in Amalfi, Sorrento, Positano etc and visit the city?
• Is there a parking in Naples easily reachable by car (maybe in suburbs) where I can safely leave the car for the day we visit that city and from where we can easily reach the center with public transportation?
