没看懂...这车辆收集是什么意思?

Collection Cups start Monday, 24 June 2024 and will run weekly.
Events called COLLECTIONS CUPs will bring opportunities to win "Collection Credits" with these, it looks you can buy certain cars to complete the collections. Think of these as GT7 Menu Collections, collect so many cars to finish the menu and get a reward. Here, you have stickers as rewards and a final sticker once all collections have been finished.
Looks like a free car will be given away to start players off, the MINI John Cooper Works GP. To give you an idea of the upcoming collections, here are the examples.
