in my experience dealing with big name dealers
they generally have 2 lines of models they sell
standard line with just basic functions and systems
premium line with all the bells and whistles, attachments and optional equipment.

example:
electric lift that has basic dash display and electric controls, standard levers, no extra sensors on motors etc,
versus one that has premium dash display and full scr hydraulic controls, fingertip levers, all sensors on motors etc.

the optional equipment depends on the mfg and what they want as standard versus premium.

these days with sales trying to maximize their numbers they generally try and push a premium line product on you first, if you want less than that you pretty much have to ask for it.
