The Museum is ok. It is interesting and it can be done in a couple of hours if wanted.
There is an area where you can watch different tv advertisements for cars and that was my favorite.
Italian visitors are noisy, but you will get used to it if you live in Italy.
The main problem for us was that the personal was very ignorant in the subject, they couldn't answer any question, were not of much help, and behave very poorly when the time of closing got closer. 30 minutes before the museum closing time a group of 7 staff members start to follow us closely. We were the only visitors left, and they start making stupid comments about how people that stay in the museum for long have weird illnesses and die. They were mentioning to us very often that the museum was "about to close" and they even celebrate when we were leaving.
Even my italian friend was irritated by this incredibly immature behavior.
