How would I start modelling?

Hey, I want to give modelling ago, I’d like to start making some vehicles for Garrys Mod but i’ve no idea what to use / what I need to start it.

Thanks.

To make them driveable… I’ve got no idea. But if you want to start modelling in general, just look for tuts in youtube, i’d suggest using 3DS Max student as its free, and probably the best modelling software out there. When you’re done with that, you can start importing in to the source engine.
