Many properties can be animated! Above you saw how easy it is to animate position by placing the object at one place in the first frame and a different place in the next keyframe.
Also, you may animate an object's transparency, rotation, size, tints and more. Imagine if you set the transparency of the car to 10% in the first keyframe and then 10% higher in each later keyframe. The car will then fade in. By changing the properties of keyframes, you are animating!
