What is the difference between Audi A6 models?

I am planning to buy an Audi A6, but I am confused about the different models available. Can you explain the key differences between them, and which one would be the best option for me? Thank you.

Hi John, the Audi A6 comes in four variants - Premium, Premium Plus, Prestige, and S6. The main difference between them is the level of luxury and technology features included. If budget is not a concern, I would recommend going for the Prestige variant, as it offers the most advanced features.
