What is the best way to prevent rust on the BMW Z4?

I recently bought a used BMW Z4 and I want to keep it in top condition. However, I've noticed some rust forming on the underside of the car. What can I do to prevent it from spreading and keep my Z4 looking like new?

You can start by regularly washing your car and keeping it clean. Salt and other debris on the roads can accelerate rusting.

Another important step is to inspect your car regularly for any signs of rust. Catching it early can prevent it from spreading.
