What is the purpose of clubhouses in GTA Online?

Clubhouses in GTA Online serve as the exclusive hubs for Motorcycle Clubs. They function not only as social gathering spots for players who choose to form or join a biker gang but also as operational headquarters from which they can manage illicit business ventures. These ventures range from narcotics distribution to counterfeit cash operations, among other criminal enterprises. Clubhouses come equipped with various amenities such as meeting rooms, garages for bike storage, and even recreational facilities. Additionally, owning a clubhouse allows players to access specific missions and challenges that are tailor-made for Motorcycle Clubs, offering unique gameplay opportunities and financial rewards within the outlaw biker subculture of GTA Online.
