The fact that it is an all-inclusive solution for fleet management as well vehicle tracking makes this software one of my favorites in our automotive industry (and I'm not even associated to any department).
It has been great working closely together over time since we started using their product at work - nothing but positive experiences so far! Nothing really specific here except maybe some minor UI enhancements could be made sometimes when accessing certain screens or features within ARGUS CSM Dashboard/Portal interface? We use ArguCSD mostly because its main purpose was designed specifically towards Fleet Management purposes; however there are other benefits such as Vehicle Tracking which can prove useful too depending upon your needs etc..
