Hi,
for moving creation you can use Allfavile Scenes 1 or 2 Library with animated car or car from Graphisoft Anniversary Colection (static car also created by Allfavile) with small object generated by my. This object is based on Allfavile free Porshe but allow to animate optional car ( you must type name of object in interface window).
Sample are available on my ftp
