Sorry about your dad.
I'll recommend two organizations that I have worked with. Either will have more than a few people who could really use a motorized wheelchair. Both should have a used equipment forum or classified section. If you have an idea how much you want for it, you could help out someone in need while getting your price.

I know Jen. She is not in charge of equipment exchanges but can get you to the person you need to talk to.
