Bugatti Veyron PT 2

I have finished up with the outline of the car so have now begin to model it section by section and so far it seems a really quick and efficient way to do this. The vertices are much neater than if I had just started out without the curves, the only tempremental thing iv stumbled across is the 'snap to curve' it just doesnt like to work very often! Has driven me mad so far but iv been persevering with it as I know it produces the best results. As technical as the car looks it has been a suprising simple process so far, although saying that I have probably jinxed myself.. Anyway heres an image to show how far with it I am:
