What is Aarya dukkha Sacca?

In buddhism what is aarya dukkha? And what’s the reason for it? Dukkha is one of four noble truth. And as I heard it’s because of the impermanence. Can in permanence be the cause for the Dukkha? Is it true? Please provide practical situations when explaining. EDIT: According to some answers, the direct answer to this question is attachment (upadana). To be more specific my question is how attachment become the cause for the Noble Dukkha? Eg: If I like a car, its an attachment. And how does that become the cause for the Noble Dhukka. EDIT 2: According to the answer given by Brian, When attached, you find something desirable and you don't want to let it go; you want to keep it for yourself, permanently. But the thing is, conditioned phenomena are in constant change, and those things will not stay the same or with you forever. But imagine a prince, and a car he owns, It doesn't matter the conditioned phenomena (Saṅkhāra) he can maintain the car as it was. So what's the dukkha in that. Please note: I'm just trying to sharp my question by providing examples, if I'm doing any thing bad, please let me know, as I'm new to this.
