Interest in the used C30 – what is there to know?

Hello and good evening. I would like to buy a new car next year. My favourites are very different, all in front are VW Eos and Volvo C30. Never thought that a Volvo could be of serious interest to me. But a test ride with the current model was really great, maybe a bit unportable, but went still (the 2.0 D with 136 hp, steering could be more direct). A visit to Check24 shocked me even more, in the insurance would be a C30 with 1.6 D e.g. considerably cheaper than my old Polo. And then still look around at Spritmonitor.de. Can stay under 6 L diesel / 100 km if you try harder. Now the question to the Volvo forum: A new C30 is not financially in question for me. What do I need to know about used C30 or generally about life as a Volvo driver? Is the maintenance perhaps particularly expensive? Are the cars more repairable than others? Are the workshops more expensive and perhaps even worse than those of Allerweltsmarken? Would I be very grateful for a few comments and thoughts that can help me in doing so, perhaps more interestingly than the C30.
