I agree with AndyPandy and Daryl, I am not a service tech, but have some forklift knowledge and a good bit of this argument is as said, getting the driver onside.
I reckon that if you are looking at the red hydrostatics, they are well equiped (e.g. full suspension seats), stable and quiet to sit in for a shift so the drivers will say they prefer them to a lot of the competition, especially the little known stuff coming in from the far east nowadays.
