What are the main differences between the BMW 4 Series and the 3 Series?

I'm considering buying a BMW but I can't decide between the 4 Series and the 3 Series. Can you help me understand the key differences between these two models?

The BMW 4 Series and the 3 Series are both great cars, but they have some distinct differences. The 4 Series has a sportier look and feel, with a more powerful engine and tighter handling. The 3 Series, on the other hand, has a more refined and luxurious feel, with a slightly more comfortable ride. It ultimately depends on your priorities and preferences.

One major difference between the 4 Series and the 3 Series is their body styles. The 4 Series is only available as a coupe or convertible, while the 3 Series offers a sedan, wagon, and Gran Turismo option. If you need more cargo space, the 3 Series might be a better choice.
