Car buying help

So, I cant buy any cars with cash, just with boost, and I have no option to change to cash. Help me please?

what??? explain better

Why can't you buy cars with In Game Cash....
you do know that there are car that can be bought with In Game cash.

A majority of cars can only be bought with boost, but there are plenty that could be bought with in game cash. Just look through the cars and you will find them. There are also some that have boost and igc versions, so switch be sure to look through the different styles.

I think that there are only shown those Boost cars: Use the arrows to adjust your selection. On the right is the IGC car (if it's available in IGC).
