How to get cars?

Hi. I’m a new Forza player and I’m playing Forza Horizon 3. Nothing special like the Collectors Edition, just the regular one if there’s any difference😀
I was wondering how to buy and exchange cars and what level you have to be on?
I’m on level 2 but can’t seem to get the “car” tab in the main menu to do its thing, not like a glitch or anything I don’t think.

Absolutely, the best way is just to keep playing through the game following the points. You’ll find you get a lot of cars and money quite quickly anyway.
