What are the different trim levels of the Audi A1?

I am looking to purchase an Audi A1, but I am unsure of the different trim options available. Could someone provide a breakdown of each trim level and their features?

The Audi A1 comes in three trim levels: Premium, Premium Plus, and Prestige. The Premium is the base model and includes standard features like leather seats and a 10-speaker audio system. The Premium Plus adds features such as a panoramic sunroof and a rearview camera. The top-of-the-line Prestige trim includes all the features of the lower trims and adds features like adaptive cruise control and a Bang & Olufsen sound system.
