PBS Systems vs CDK Global
PBS Systems was named in 22 of 150 answers about dealership management systems; CDK Global in 90. There was no question where PBS Systems was named and CDK Global was not. PBS Systems was named by ChatGPT, Claude, Perplexity and Google AI Mode only.
CDK Global is the most named checked vendor in dealership management systems in this release, so every other vendor in the category is compared with it.

Measured head to head
No question in this release asked the engines to choose between PBS Systems and CDK Global; the counts above come from the ten buyer questions.
What the engines said about each
Assuming you mean replacing CDK’s dealership management system (DMS) at a U.S. dealership, I’d shortlist Tekion, Reynolds & Reynolds, Dealertrack DMS, and PBS Systems.
One sentence per engine at most, chosen by a fixed rule: the first full sentence naming a checked vendor, read in run order. Every answer in full: DOI 10.5281/zenodo.22907695.
What to do with this
PBS Systems claims its record, free, and runs the free check on its own name. The widest gap is on “Tekion vs CDK, which DMS is better for a franchise dealer”: that is the question to fix with Answer Repair, $490.
