Its real easy to get the wheels to work using the grouping tool in Poser. Just select the wheels polys and spawn them as props, invert selection and spawn the rest. Walla, seperate wheels and body. Delete the original mesh, use the joint editor to set the pivot points on the wheels and your done. Does it have an interior and engine? If not making the doors and hood work may be a waste. Send it on and I'll take a look at it. Is this a model of your real car? I generally use Maya so I would have to convert it to work on it. Would you need it back as a 3DS file? Email me and well talk about what I can help you with, Duddly01@hotmail.com.
