Long-term experience DS4 Gen2 / Child Diseases?

Hello, I have recently looked at a well-equipped DS4 as an annual car and made a short test drive. It was a DS4 PureTech 180 Performance Line Plus. I already read some posts here in the forum, but so many posts are not. Are there positives like negative experiences with the vehicle (generally) and the motorization(interested me especially) ? What should I pay particular attention to when buying? The operation is a bit “different” and for me not t absolutely intuitive, maybe I just have to deal with it more. I have not yet found out the true meaning of the small screen, except the navigation card to “zoomen”. Thanks already for feedback.
