I no have Beta version for Joomla 1.6 .
But EXP Autos Pro component for Joomla 1.5 use MVC cheme this scheme use Joomla 1.6 and no problem for update.
I update component for Joomla 1.6 and create new version EXP Autos Pro component.
The new version EXP Autos Pro component will be many changes, and therefore require time to update the component.
