i need help making a car dealership?

so, i am working on a car game, but the problem is: i don't know how to script at all. So the first thing i want in the game is a car dealership, but i want to make one so you go up to the guy behind the counter, it opens a Menu, and there you can select wich car you can buy, also want to make it so the game saves the car in your inventory, like in vehicle simulator you have the phone, i want to make something like that. you can either just help trough this site or add me in discord. Discord would be easier so i can explain it better. (my english isn't that great tho, i live in belgium). annyway, thanks for making time and reading this.

This website is used to help you with a problem or a mistake you made in your script, even asking how to do something isn't allowed. And you're just here requesting someone to make you a game. Sorry this isn't allowed there are other places to do this.
