What are the key differences between the Audi A4 S Line and the A4 SE models?

I am considering purchasing an Audi A4 and am curious about the differences between the S Line and SE models. Are the differences purely aesthetic or are there also differences in performance and features?

The Audi A4 S Line offers a more dynamic and sporty appearance compared to the SE model. In terms of performance, the S Line has a firmer suspension and more responsive steering, making it better for driving enthusiasts. Additionally, the S Line includes features such as larger wheels, sport seats, and a sport steering wheel for a more engaging driving experience.
