You might want to rethink this as it’s not OEM and you’re looking for a non-OEM airbag. I wouldn’t know where to direct you to find such a thing but I also wouldn’t recommend it. Safety first.

The m4 is better built, will hold value longer, and has a better interior and tech. Appearance is a subjective thing so it’s up to your personal preference but real car enthusiasts can easily spot the difference between an M4 and a 4 series. If you’re more familiar with BMW then that’s a big plus as it will aid you down range in almost every way. From a driving standpoint, the f82 performs better (better computer to manage and deliver the power in a safe and controlled manner), while the C6 is notorious for losing traction under hard acceleration. The Vette’s V8 gives it a better sound BUT it’s also looking dated and isn’t much of a head turner in this day and age.
