I've tried getting some free models to see if i understand but idk how the driverseat works and i just wanted to know how to put the weels and make them rotate
Probably the best alternative is to use BodyMovers. They require some scripting, but it's not too complicated, and you can get similar results to a basic car that is powered by Hinges. Unfortunately, Roblox deprecated them not too long ago, but you can still get them from Toolbox.
Another, newer, alternative is Constraints. I'm not familiar with them very much, but I heard that they are great and are easy to get the hang of, plus they give you more customisation options, which is nice.
Whatever you choose, you will still need to glue the parts together. Old Welds are also deprecated, but you can download a Plugin which lets you use old Surface tools again, including Welds: https://www.roblox.com/library/5070921519/Surface-Tool If you don't wish to do that, then your only option is to use Weld constraints.
