Are you able to exchange cars at the dealer after buying it?

I got a used car at a very small dealer place.
they have very little cars to choose from. My old car stopped working and got a white Kia sorento. But after a week of driving it, it feels huge, no need for 3 row seats, and work daily far and need a small car. I have no kids no family, and now feel like an old lady with this sorento. The inside is elegant , comfy seats, feels warm. But I also want work on free time delivering food and need a small car. It drives quiet but too big to maneuver.
