Is there a market for hand controls?

I currently have a converted van and looking to get a new one for a reason I won't get into. I am a C5 quadriplegic and use EMC hand controls. Is there a market out there for selling my van with less than 25,000 miles with the hand controls installed? I realize it's all custom fitted, but it would seriously take less than a day for a technician to move the tiedowns and move the trip pin/touchscreen for a new user. Those controls were over $60,000 on their own so if someone was paying privately, they could save a ton of money. Of course the dealership suggest that I pay them to remove all of those controls and just sell the van as a ramp van. What are your thoughts?
