What is the difference between the Audi A4 S Line and the A4 Black Edition?

I am considering purchasing an Audi A4 but I am unsure which trim level would be best for me. Can someone explain the main differences between the A4 S Line and the A4 Black Edition?

The main difference between the A4 S Line and the A4 Black Edition is their exterior design. The S Line has a sporty and sleek look while the Black Edition has a more aggressive and unique style.

In terms of features, the A4 S Line and the A4 Black Edition offer similar options. However, the Black Edition includes upgraded technology such as a Bang & Olufsen sound system and a virtual cockpit.
