2021+ Cooper and Countryman Question

Due to an unfortunate accident, my 2014 Mini Cooper (F56) is moving on to car heaven, so I've been looking at CPO Mini Coopers and Countrymans. I heard typical problems include engine mounts and some pumps/housings, but is there anything else? Any model-year production issues or things to watch out for around the 2021+ models?

Thanks all, and rest in pieces Mini (2014 - 2025)
