Our store is considering switching DMS providers. We are looking at DealerTrack, R&R and ADP. We are currently on Quorum and just are not happy with its overall performance. Everybody here seemed to like DT from the demo but I am worried that they are still having trouble keeping up with all their new customers technical support-wise. R&R and ADP are proven products but are they worth the extra cost and long-term contracts? Would really like to hear from some people and their opinions - good and bad. It doesn't look to me like any DMS is totally bullet proof.
