How can I create a 3d preview of my pawn that I'm building in game?

So I have a vehicle based game.

I want to be able to drive to a spot to open up a menu that allows you to customize the car. Wheels. Body. Weapons etc.

But I want to have a preview of the car and all of the assets that are being added onto it in real time as you select them from say, a widget blueprint.

Hope could I go about doing this?
