Modena, Bologna Suggestions

You could go to Parma and also to the nearby castle of Torrechiara for its many painted rooms and its views. Verona is in the Veneto, but only a short train ride from Modena. If you like ceramics, go see the ceramics museum in Faenza (and the shops selling ceramics).

What a pity you arrive in Modena after the Sciocolà Festival!
As food producer is very interesting visit a Parmigiano-Reggiano dairy, but better been done at early morning.
A prosciutto producer in Modena or Parma could be interesting too. In November in Savigno there is even the truffle festival, but mostly during the week end.
You know that near Bologna there is even the Gelato university?
And of course a lot of restaurants and local traditional food. In Autumn you can visot the Modena's hills ide and try Borlenghi, Ciacci and all the traditional chestnut products.
As motors there are a lot of museums: two Ferrari, two Lamborghini, the private Maserati collection, Pagani atelier, Ducati museum.... On top of that you can visit even some factories: Lamborghini, Pagani, Ducati....
As suggested by other people there are even wonderful museums Pilotta in Parma, Estense in Modena, Pinacoteca in Bologna...), and castles (Torrechiara, Fontanellato, Vignola...)

I am wondering which car museums and tours are easier to visit or schedule. Also which car attractions are most popular? Thank you.

Hi, Giangilberto from Milan, as a keen porcini picker, I can highly recommend you try them, especially because they're seasonal. Numerous new mushrooms are currently appearing throughout the Ligurian and Tuscan-Emilian Apennines. I myself went picking them this weekend, and if the weather holds, they'll keep coming well into autumn.
So, my advice is to enjoy a good porcini tasting session, considering that in Italy, porcini mushrooms are called the "il re dei boschi" (the king of the woods).
The Apennines around Modena have forests where porcini mushrooms find their natural habitat.
Or, if you want to travel a little further, about an hour and a quarter by car can take you to the Val di Taro, long considered one of Italy's largest porcini mushroom producing areas.
Italian culinary excellence offers an iconic dish that combines the tradition of egg pasta, a heritage of Emilia-Romagna, with porcini mushrooms: the delicious tagliatelle ai funghi porcini (porcini mushroom tagliatelle), an autumn dish not to be missed.
Plenty of restaurants have porcini on the menu right now.
In the areas where they grow, they're incredibly fresh and local. Just be careful with restaurants outside the area, the porcini may well be imported, often frozen, from Eastern Europe and they are not the same thing.
Ask the restaurant owner where they come from (Sono porcini di zona?). In any case, in the hilly areas round Modena you're almost certainly getting local ones.

While staying in Bologna this past July, we did the Lamborghini Museum and Factory Tour. It's less than an hour drive from Bologna. The museum is on the smaller side and the factory tour takes about one hour, so the whole experience wouldn't take longer than 3 hours. You'll want to book early as factory tour slots can fill up.

The Lambo factory is only a 10 minute drive from Caseificio Parmigiano Bio Reggiani dairy farm, which also does tours and tastings. Would recommend. Lump the two together (like my family did) and you'd have a pretty full day with time to return to your home base for dinner.

Hypercar manufacturer Pagani also offers guided tours. I didn't go but heard good things. It's only a 20 minute drive from Lambo.
