As you are winding it you are converting kinetic energy (the winding) to potential energy (stored in the spring). When you let it go, you are doing the opposite, so converting the potential energy in the spring back into kinetic energy, and hence the car moves.

Actually if you think about it the starting energy is your body burning chemical energy to power your muscles to wind the mechanism up- this is then converted to potential energy (the spring tightening) and sound (the noise of the winding) with a small fraction of heat caused by friction - the potential energy of the spring is changed to kenetic energy (the movement of the car), sound energy (the noise the car makes as it moves) and again a small amount of heat as the mechanism unwinds and the friction of the clockwork warms.
If you think about it you could add more like the potential energy of the air the car moves out of it's way as it travels
