Constant Movement Illusion

For one of the projects I am currently working on with Unreal 4, I was wanting to recreate the title screen for Wario Land 4. ( Note: Only the part where he’s driving down the desert.

I already have all of the art assets for this completed, however I got stuck/lost in the process of animating the scene in a way where it looked as if there was constant, looping movement.

Any tips/tricks I could use?
