We went through this 'fun adventure' a few years back and I can tell you be sure you touch on all aspects of the dealership and have all your departments really involved. We went from the old EDS/ADP-ARG system and decided on ADP DRIVE. The conversion was a pretty bad experience but after time we have learned to use the system with all its odd things and defects... many defects haha. One of the best things we did do was hire the Gillrie Institue to assist us with our Contract. It was was/is money well spent. It paid for itself with the savings within the first few months. I would not go through a contracting without them again. Welcome to the Paul Gillrie Institute - The Paul Gillrie Institute.
