Implementing the ability to add tints to your cars would be awesome. Make a shop called Asylum Customs(Los Santos Customs from GTA V) where you can add different percentages of tints on your windows. 5% tints could make a person be unknown when driving around. Could also allow new roleplay scenarios for police eg, pulling over someone for their tints and that being probable cause to search the vehicle as it is in real life in some states. I just see this as more of a cosmetic thing but would also be dope since we can't really add much to our cars.
