Potential New Customer Looking for an ARAS reference

My company is very interested in ARAS PLM.  We will intially be using it to vault and manage CAD (Solidworks, and Creo) and also to use it for Engineering Change management. We are consider one other provider and because some of us already have experience with that providers product we don't need to get a reference company to talk with.  We are a small manufacturing company in the auto industry.  We have 28 CAD users and another 50 or so people involved with the ECO process. Thanks for your help.
