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

I am considering buying an Audi A4, but I am not sure what the difference is between the regular A4 and the A4 S Line. Could someone provide some insight?

The A4 and A4 S Line are essentially the same car, but the S Line adds some sportier features such as a lowered suspension, larger wheels, and sport seats. It also has a more aggressive exterior style.

One of the main differences is the price. The A4 S Line is more expensive due to its added features. However, if you value the sportier design and feel, it may be worth the extra cost.
