Your getting butt raped if you think a clean used m3 wheel is $500. You dont need anything except the wheel and trim. Your airbag will be a direct swap along with your wiring harness. I paid $220 shipped for mine off a salvaged car. And the gap is about as big as the search button, please use it.
Edit: Also, there is much more to an M wheel than just the trim. It's worth the coin.
