Steam ID for access to vehicles

Hello, I was wondering if there was a script or a plugin that allows you to use someone’s steam id to allow them access to certain vehicles. What I mean is so someone can say use 2 different addon vehicles but not any other addon vehicles depending on their steam ID, but other people can’t access the vehicles that a different person can but they can access vehicles other people can’t. I understand that it sounds confusing but any help would be appreciated!

Pretty sure you will have to create something custom to suite your needs (which I don’t 100% understand) but it sounds like a niche need.
