What is the difference between the 2 Series and the 3 Series?

I've been looking at BMW models and I'm having a hard time understanding the difference between the 2 Series and the 3 Series. Can someone explain?

The main difference between the 2 Series and the 3 Series is their size. The 2 Series is a smaller, compact car while the 3 Series is a mid-size sedan. The 3 Series also offers more power and a smoother ride.

Another key difference is that the 2 Series is available as a coupe or convertible, while the 3 Series is only available as a sedan. If you're looking for a sportier driving experience, the 2 Series may be a better option.
