Im playing on the latest version of maniaplanet, and on the latest version of TM2.
i found all the models in the ManiaPark website
This is an example of a not working model http://www.maniapark.com/ressource.php?id=3476

I've downloaded lots of cars from maniapark, but only a smal percentage of them works ! many just show me the grey default car, can someone help me ?
