Load this as a background image and draw a mesh over the side - in a similar way to the car tutorial but here you want more detail.
Extrude the shape with copies set to 2 or 3 to make half the car. It's then a case of shaping the vertices along the edge.
More extrudes will add more detail and the more time you take on the initial side panel will help.
You could also start by drawing an AC3D Mesh object and moving the points in line with the side image.
