Does anyone have a list of cars that needs to be downloaded for the physical edition?

I didn’t know until I bought the game that there was an 18GB+ download for the game which was for downloading many of the cars. I can’t download anything over 5GB, so it’s not even possible to do. I’m just wondering if the cars missing matters to me and if anything else is missing other than the 137 cars I’ve read needed to be downloaded. I’m just trying to figure out if the game needs to be returned or not. Thanks.

it’s not just the cars, it’s the rest of the game

You’re saying the game isn’t even playable without the download? That’s terrible if true.
