Following up to say that I really appreciate all of the guidance and insight you all have provided here. I ended up passing on the car that I originally posted about here, and tomorrow I will be looking at one being sold by a private party. It is spec’d perfectly for me: 2018 M3 Competition package, 6MT, executive package, Sakhir Orange extended leather interior, moonroof, factory carbon front splitters, rear diffuser and rear spoiler, and the oem 666m wheels that came with the car. 39k miles and no reported accident history. If all goes well, by this time tomorrow I’ll have some photos to share
