Garage Plus costs 399 Robux and yields a 200% multiplier to baseline part income. It also decreases the AFK (Away From Keyboard) penalty reduction metric by 50% and expands maximum vehicle inventory capacity by +8 slots.
The +8 inventory slots are the headline benefit. Without Garage Plus, players are forced to wait for individual auctions to clear before initiating subsequent repairs. With Garage Plus, players can hold multiple appreciating assets on the auction block while actively engaged in repairing another chassis.
The 200% part income multiplier means that for every container purchased, a Garage Plus owner receives effectively three parts' worth of value from a non-owner. This single multiplier shaves weeks off the Legendary vehicle grind.
If you only ever buy one gamepass, buy Garage Plus. The VIP gamepass is the second-strongest option for active players, applying a 20% net revenue multiplier to fully repaired vehicle sales and a 1.25x walkspeed bonus.
