Ooo, speedy reply (No surprise really considering we're nearly neighbours!)

Some further Google searches has heralded another result that Hexagon 2 from DAZ 3D will also let me model cars. So there are some cheaper options around that I'm pretty pleased with.

I'd like to hear from people who use Carrara or Hexagon 2 to hear what they think of the programs. A run in the demos of each program will help me decide, but I like hearing other people's experience with the programs and the results they get.
