It does look like just a bolt on add-on to microsoft dynamic CRM. And it looks like it might be geared towards the hotel industry perhaps? Not sure.
I personally have not heard of Microsoft's Dynamic CRM being successfully deployed at dealerships. From the guys that I have heard that use it they hate it. Which, I think is just because they are trying to use it for something it wasn't built for (i.e. square peg/round hole). That is not to say it is not a well built system. Just not industry focused.
You are usually better off going with a good automotive CRM that is built with auto dealerships in mind and that integrates with your DMS, has the ability to automate your leads that come in, is accessible online from anywhere, etc. and is flexible enough to be customized to your dealership.
Are you currently using a CRM?
