What is the difference between an Audi 80 and an A4?

I'm considering buying either an Audi 80 or an A4, but I'm not sure which one would be a better fit for me. Can someone explain the main differences between these two models?

The biggest difference between the Audi 80 and A4 is their release date. The Audi 80 was originally produced from 1972 to 1996, while the A4 was introduced in 1994 and is still in production today. This means that the A4 has newer technology and features compared to the older Audi 80. However, some people prefer the classic design and feel of the Audi 80.
