Collection of different types of data in a relational database

Let's say I have a table Cars (with columns such as model, make, year, etc.), a table Books (with columns such as name, author, ISBN, etc.) and a table Wines (with columns such as name, appellation, region, vintage, etc.) Now, even if these tables don't seem related at all, I want to make a collection of all these things called "My favorites things in the world". In this list, I will find cars, books and wines. If I only wanted to have lists of cars, I would create a table called Car_Lists with id and name + a table called Car_List_Items with id, car_list_id (foreign key to the id in the table Car_Lists) and car_id (foreign key to the id in the table Cars). Here, as I want to have a list of different types of things, I don't really see how this could be done. So my question: How would I represent that with a relational database?
