From personal experience, most of the dudes that do nonsense like this live with their parents and buy used muscle cars like Camaros and Mustangs or high mileage luxury cars like AMGs, Ms, and G35/37s that have been hit with 30-50K of depreciation. If the cars are new, there's a good chance the drivers are drug dealers. They'll buy these old cars and post all over IG with them with hashtags exactly like this dude in the C63
I used to know too many people like that until I cut them off for doing all this @$## around me and putting my career in jeopardy.
Note: I'm not hating on or looking down on people who buy used cars or live with their parents; just saying that the people who behave like this and flaunt all over social media are usually the most average to bummy dudes in regular life.
