Thank you Milel007. The model still has room for improvement: it lacks an interior and an engine, and parts such as the hood and doors could be animated. As ever: if I find the time... :)

thanks riveter, I've worked a bit more on my local copy of it. Pieces such as the side trim are still curve objects so to clean it up for export you would probably need to convert them to mesh objects (alt-c). The side trim was a nice place to start on this project as it is visible in all three views. And using a curve to create it kept it smooth. I then built the panels and doors to match this. The headlights use a grooved mesh with a glass material to create the 'fresnel lens' look.
