Yes, I think it is worth a visit. I am not even a car person but thought the museum was very well done. We rented the audio guide at the museum and found that it added to the experience. I was surprised that even on a weekday it was fairly crowded but I think it was due to a number of school class trips that were happening that day. We took public transport from downtown Turin and it was very easy to find our way. We also combined it with lunch at Eataly which is about a 10 minute walk from the museum.
If I could add another Turin site that we enjoyed, it was the Lavazza Museum (https://www.lavazza.com/en/lavazza-museum/discover-the-museum.html). This was really fun -- covering manufacturing, agriculture, marketing, design and artwork and ending with coffee tasting. Here, we also did the audio guide and found it informative. I did see a few people with actual tour guides so perhaps that can be arranged with Lavazza. It is in downtown Turin but in a neighborhood slightly outside of the central district. But we walked to it, from our AirBnB it was about a 20 minute walk or so. Highly recommend and since returning home I've even been buying Lavazza coffee for my iced coffees in the summer.
