Need Help with Car Parking Multiplayer Game!

Hey everyone,

I've been playing Car Parking Multiplayer for a while now and I'm loving it, but I've got a question that's been bugging me. How do you unlock the premium cars in the game? I've been grinding for a while, but it seems like there's no clear path to unlocking them Car Parking Multiplayer: Buying and Selling Cars. Do I need to reach a certain level, complete specific challenges, or is there something else I'm missing? Any tips or advice from seasoned players would be greatly appreciated!
