Making a car with nurb or mesh?

I want to make a concept car type (Not a real one). I try to make one with mesh but when I smouth it all the thing became very weird and I have difficulty to use nurb so some know a tutorial other than this one :
because the text in this one is hide behind the images so I dont understand all the thing. I searched in the blender knowledge base but did not find something!
Thank you in advanced!

I would do a very simple vertex model and use the subdivision-surface-tool to smooth the model.

The tut shows that the guy has loaded a picture in the background, isn’t it? Do that too and model a very simple surface. to check if the subsurface fits the picture you only need to toggle the button ‘on’.
