Wow thanks everybody for all your ideas. Markschum I will give the CR2 editing a go I like the idea of a seperate dial to control the steering of the seperate objects. As Plutom states I know it can be done because most car models for sale here include this feature. I have managed to build the car in a 3d package and import it. The next step is picking the bits of Poser I need to add to create a bit more functionality.  This is an excellent headstart :-)
