What are the main differences between a Audi 80 and an Audi 100?

I'm deciding between buying an Audi 80 and an Audi 100. They seem quite similar, but I want to make sure I understand the unique features of each model before making a decision. Can you help me understand the main differences between the two?

The Audi 80 is a smaller and more affordable option compared to the Audi 100. It also has a sportier design and is known for its agility on the road.

The Audi 100 offers more luxury and comfort features, such as a larger and more spacious interior, advanced technology, and a smoother driving experience.
