Where to sell a handicap van?

I have a handicap van that I'm looking to get $70,000 (it has already been appraised for) and It only has 7,900 miles on it. The bad part is, is that it's more of an option for people looking for luxury and it is not the most practical option. It has a 20" TV, leather interior, GPS, and other luxurious features. My problem is that if it were a normal modified van worth 20,000 or less, most people would be interested. But since it is not a practical option for most people, I don't know where to sell it. It's not exactly something one just puts on Craigslist. So what site would be the best to sell such a van as this?
