Hey Modders, How Do You Make Vehicles In RoR?

[Smarty]

This is kind of an off-topic question, but I've heard that a BUNCH of work goes in to making just a single, good car. I've been told that just making the base engine, suspension, etc can take months. So, I was wondering what the process is for making a vehicle, like making the assets, designing the parts, and so on. Also, thanks to all the people out there that make the vehicles for this game. Especially the BusFag. That vehicle just radiates pure, golden quality.
