What is the difference between Audi A6 and A6 Avant models?

I am considering purchasing an Audi A6, but I am unsure of the differences between the Audi A6 and the A6 Avant models. Can someone provide some insights into their distinctions and which model may be the better option?

The main difference between the Audi A6 and A6 Avant models is that the A6 Avant is a wagon, offering more cargo space and practicality. If you prioritize cargo space, the A6 Avant may be a better option for you.
