What is the difference between Audi A6 Quattro and S line?

I am considering purchasing an Audi A6, but I am not sure what the difference is between the Quattro and S line versions. Can someone explain the technical distinction and which one is better for my needs?

The Audi A6 Quattro is an all-wheel drive system that provides superior traction and handling in various road conditions, while the S line is a trim package that offers sportier exterior styling and upgraded interior features. If you live in an area with harsh weather, the Quattro may be a better choice for its enhanced performance and safety. Otherwise, the S line may offer more visual appeal for urban drivers.

As an Audi mechanic, I can tell you that the Quattro is a more advanced and complex system that requires specialized maintenance and may have a higher cost of ownership. The S line, on the other hand, is more straightforward and easier to maintain. Consider your budget and maintenance preferences when choosing between the two.
