You can purchase/make a parking stopper for your car.

If you are going to make one, get an old piece of carpet and short piece of wood at least 1 inch in diameter. The carpet needs to be long enough that when folded, it will fit under the tire. Loop the carpet around the stick with the excess carpet toward the garage door. The weight of the vehicle will hold the stopper in place. Once you get to the stick, you will feel resistance to moving the car further forward.

As pointed out by Holroy, this method is subject to sliding around. Some glue would help to prevent the sliding. Your flooring will dictate the type of glue necessary.
