AI vehicle question

[FakeZapata]

In individual races, can I choose what vehicles I am about to compete against or is it necessary to replace the cars?

[Franch88]

To change the opponent vehicles is always requited to make a mod on purpose, changing the basenames inside the respective races .aimap and .aimap_p files.
This isn't possible to do in the game before you start a race with opponents.

I am aware it can't be changed ingame, since I have been playing it 15 years. Good thing the solution isn't to edit the cars themselves. Is it the same procedure if the cars aren't from the basegame?

Yes, the basenames are unique of each player/AI cop/traffic car, it doesn't matter if of default game ones or add-on ones.
