SLC 43 AMG purchasing advice

Good day together, I’m pretty sure that I’ve asked this question in this forum, but I can’t find this topic in my account anymore. So the question again. I’m currently driving a SLK350 R171 MOPF. And I’m thinking of swapping it for an SLC 43 AMG. If you drive such an SLC 43 or have been possessed or driven, you can write me your experience. Are there any topics that you should consider when buying a used one? My current SLK 350 has been driving for 8 years and except for inspection and normal wear parts, I have never had any problems with this vehicle. I had already thought of buying the successor as SLK 55, but I think that the SCL 43 is more dynamic with Turbo. The SLK is my second car, mainly I drive a Golf 7 R Facelift, with which I can be sure that the SLK 43 is more dynamic with Turbo. I’m happy.
