I would assume the parking garage has 30 spots, one for each person in the session, and the personal garage has 10 slots, but 3 purchasable floors (not dissimilar to the Office, Nightclub, and Arena garages).
Then there will be a personal garage, which the neswire says can at least hold 10 cars based on their wording. It seems there will be a parking garage for all players to park together, car meet style. Well the parking garage and your personal garages are two separate things. Seems like we won’t know until Tuesday morning, but it’s a fun discussion. I have a master plan of how I want to move all my cars around, plus add in the new ones, but it assumes we’ll get at least 30. It’s on par with both the Nightclub and Arena updates, and the DLCs have had 20-30 cars. There is a small chance that the DLC will be announced in November, but a December launch is virtually guaranteed.
A large majority of the winter updates have dropped during the month of December, so it is a safe assumption that in 2023 it will be no different. Personally, I’m hoping for at least 30 spots. The GTA Online 2023 Winter Update will most likely release in December this year. What’s everyone’s thoughts on how many parking spots there will be in the garage? I know I saw something that implies ten spots, but maybe that’s just the base level that comes with the penthouse, and you can add more?
