Wow we have been getting a lot of FPSC stuff coming through. I can see you've used animator, and am happy you're willing to give stuff away, the model could be better in my opinion, but it is a good start.
I have used anim8or in 2/3 years, so I wouldn't ask me how you would do these things. Looking at your model, it appears that you have just draw the out line polygons and extruded. Now, in Anim8or you can apply a reference image to the background, this is extremely useful if you want to get the shape of the car. I'd find an option like that. The is also an 'knife/cut tool' in the toolset, now you can use that to 'score' along polygons splitting them into sets of twos, from there you can move points/vertices to new positions, making the car look smoother.
Hope that helps.
