How often should I get my BMW 3 Series serviced?

I just bought a BMW 3 Series and I want to make sure I am properly maintaining it. How often should I take it in for servicing and what should I expect during a routine service appointment?

As a new BMW owner, it's important to follow the manufacturer's recommended service schedule. This will usually include an oil change every 10,000 miles and a more comprehensive service every 20,000 miles. Be sure to also check your owner's manual for specific guidelines based on your driving habits and environmental factors.
