What is the difference between Audi 80 and 90 models?

I've been looking to purchase a used Audi and I've come across both the Audi 80 and 90 models. Can someone explain the key differences between the two? Are there any notable advantages or disadvantages of one over the other?

The main difference between the Audi 80 and 90 models is the size and engine. The Audi 90 has a larger engine and offers more power and acceleration, while the Audi 80 has a smaller, more fuel-efficient engine. It really depends on your personal preferences and driving needs.

One major difference between the Audi 80 and 90 is the suspension system. The Audi 80 uses a simpler torsion bar suspension whereas the 90 uses a more advanced independent suspension. This means the Audi 90 may offer a smoother ride and better handling.

The Audi 80 and 90 are very similar in terms of style and design. The main difference is that the Audi 90 offers more standard features and options, making it a more luxurious and high-performance option. It ultimately comes down to your budget and desired level of luxury.
