What is the difference between the GT and GT-Line trim levels on a Kia Ceed?

I am planning to buy a Kia Ceed, but I can't decide between the GT and GT-Line trim levels. Can anyone explain the technical differences between the two and help me make my decision?

The GT trim level offers a more powerful engine and sportier exterior styling compared to the GT-Line.

If performance is important to you, go for the GT trim. But if you are more concerned about fuel efficiency, the GT-Line might be a better option.

The GT-Line has a more luxurious interior with features like leather seats and dual-zone climate control, while the GT focuses more on performance.
