What is the difference between Audi A2 and A3?

I am stuck between choosing the Audi A2 or A3. Can you help me understand the key differences between these two models?

The main difference between the Audi A2 and A3 is their size. The A2 is a compact hatchback while the A3 is a sedan. If you prefer a smaller and more nimble car, the A2 would be a better choice. However, if you need more space and a more luxurious feel, the A3 would be a better fit.

Another difference to consider is the price. The A2 is generally more affordable than the A3, so if budget is a concern, the A2 would be a more practical choice.
