Is your floor poured inside the walls, or was the slab poured and then the garage built on top of it? If the garage was built first, and then the floor poured, you can actually level the floor by raising the low point. Not sure of the exact science behind it, but several contractors here drill holes in the concrete and pump concreted underneath it to raise the floor. Barring that, then your method should work just fine.

Of course, the raising won't do you any good if the floor was poured that way, but it does work well for slabs that have sunk.
