I agree with Linn Boyd that all the CRM's I've seen fall short in terms of usability and technology.

Sorry for the blatant self promotion :-)
I would like to add-in... I will definitely agree about the ADP and R&R systems are not worth looking at and now after close to a year with VinSolutions they are a big NO! They put on the greatest demo and had everyone on board but soon after launch the problems started and the majority never fixed. Their desking tool is worthless at best. Their support has gotten worse since AutoTrader bought them even thought they try to tell you nothing has changed.
We are now shopping around for a new inventory manager, desking tool and CRM since we are leaving Vin and will be doing some heavy research. Being that we are a Mercedes dealer they have a pretty short list of approved vendors (you can only have you MB internet leads integrated with your CRM if it is an approved one) so we are limited as to we can go with. Thankfully the list includes companies like E-Lead CRM, Autobase, Dealer Socket, Car Research XRM, UDC Momentum which all seem to be pretty well respected out there. They also have Advent Resources which I have never heard of.
I really wanted to believe in VinSolutions as they have an amazing package of products but they really let us down.
We are shopping for a CRM at this time, too. A good source of information has been the web site drivingsales.com. They have a "Rate your vendor" section with lots of vendor ratings and comments. I'm learning more as I read what's posted on Dealer Elite.
I am going to check that site out now. Thanks for the info.
