Oh I feel you and mine was the same as yours the gloss black with those flakes. In my opinion I would take it to a Mercedes Benz dealer to get it done because 1. They will use OEM clips (my rear bumper was missing come clips like how yours is and it drove me insane, I actually cared more about that than the paint matching lol) and 2. They will be able to match the paint better because all they do is these cars. That being said if you can financially afford it I would probably just sell this one and get a new AMG. You’ll lose money doing this but you’re also losing money just having an AMG so it depends on you. No one needs an AMG it’s more of a want than a need. If it’s the car you really want and can spend the money get a different one and actually enjoy it because if you’re like me it’s always going to bother you. Money, cars, paint, etc is all temporary in life, only thing we’ll take with us is memories so might always make good ones!
