How do I randomly create an object in a set of object

Hi you all i am currently making a top down racing game.the enemies car is a sprite(rectangle) that i randomly create above the viewport and they come down toward the player.i have some other sprite objects carGreen carPurple and carRed from which i wish to create and set their position to one of the created rectangles.So that ill have an enemy rectangle created along side with a carGreen sprite or carRed.All of this the game must randomly generate and attach ...How do i achieve this?

Would using frames or animations work for this?

Just create the enemy sprite and pin it to the rectangle..

On creation set either the animation or frame to choose()

LittleStain i will try but it means i shouldnt have seperated all the enemies into different sprites with their own animations...is there a way to do this with families? as i intend for the main player t be able to control those enemies when its main car dies

LittleStain finaly i went along with your solution i bundled all the enemy animation together and used your algorithm to generate them randomly thanks bro
