Import Auto Inventory and export formatted data to my site.

Looking for a script/system that will be able to import an auto dealer's inventory through their individual dealer management systems (Such as ADP, Reynolds, CDMdata etc) and export it to a website that will display their inventory formatted nicely on their own dealer page. Basically looking for something that can do what [login to view URL] and [login to view URL] does. They take dealer inventory data and post it to their site all nicely formatted. I have an existing site where dealers have their own profile pages. I'd like for a subscribing dealer's inventory data to be pulled automatically at intervals I can set, then automatically update the inventory displayed on my site. I need something that is seamless and low maintenance. Once I place the code or widget on their page, everything should be automatic. Control panel for me to manage every dealers individual settings is a requirement.
