Dealership System V2 v1.0

The idea is great, the Ui looks great and the features are awesome. But it does not work,i've spent some time trying this sytem to work but no answer. the test drive works but when i want to buy a vehicle, with money nothing happens when i confirm, and robux message does not pop up. I havent really seen an instructions script because i might missed something but i dont know. the concept is great and it would be awesome if you could get it to work, Thanks. I've also tried adding you on roblox and discord.
