I've seen it from both sides. Some partners aren't great for dealers at all and only are in it for themselves. Some partners are great for dealers but bad actor dealers try to use them looking for an 'easy button' to sell more cars etc. What I've personally seen is the bad actors lack the ability to put processes in place or lack the change management to use the tool given to them.
You can buy any fancy tool off the shelf to help build a boat. But if you don't know how to use it properly the boat isn't going to float.
Sometimes the tool is too progressive or complicated and the usage can get lost in translation. Whose fault is this? The vendor for making a complex tool or dealer who hired inflexible management unwilling to learn new skills?
My gut is most new tools being developed are technologically outpacing a lot of traditional dealerships ability to process them. As I know you've learned, being complacent and not asking questions isn't going to cut it these days.
