I recently attempted several times to make wasd cars in wire but it was irritating and hard so i would like for someone to make an easier wasd car stool

Or you could just use one of dozens of vehicle packs on garrysmod.org?

i like making my own cARS

I don’t know how using someone else’s tool is making your own stuff, but actually what you’ve been asking for has already been made.
This allows as much customization as you’re going to get without building your own contraption.
