The Family Garage allows family members to store and remove vehicles. There may be a minimum family role required to remove a vehicle, it's up to family bosses or VIP members to decide this for your family.
When a family is started the Family Garage cannot hold any vehicles. Any VIP Member or Boss can upgrade the Family Garage by going to the Family Dashboard then Upgrades tab. The cost to upgrade is $100,000 per vehicle, up to a maximum of 50 vehicles.
When viewing the family garage you can view all the details for the vehicle including how tuned and damaged it is.
