Not gonna lie, this for me is at the moment the best drive experience in AC, and that means in all sim racing. I've put together a solid field of 22 cars (1989 GTO season, I think there are 10 or 11 different cars in total), BOP-ed them with CM ballast and restrict settings so they run close to each other on virtually any track (tested on some 15 USA tracks at least), and it is a blast to drive and especially race. Some are faster on fast, some on technical tracks. The races I had on mid Ohio and Watkins Glenn are probably the best ai races I had in a long time. If anyone wants, I can post here how I balanced them and where I got all the cars. To save people the trouble of doing this themselves.
