Assess your expected van needs carefully and if you feel you really do need a van for daily use, then based on my experience, I also recommend buying used. In addition to being much cheaper, if it is not quite what you need, you can probably sell it for about what you paid for it if you shop carefully and buy privately. I bought my first side-entry wheelchair van in 2005 on the Internet. It was a Chrysler Town and Country converted by Braun. It was a 1999 model and had 45,000 miles. I paid $16,000 US for it. It has lasted me 7 years and, aside from replacing two transmissions, has been relatively trouble-free and now has over 175,000 miles on it. I am retiring it to my daughter's place so I will have a van when my wife and I fly out to visit.
I have just purchased my first new car in my life. After much research into Honda and Toyota, I felt that another Chrysler van was best for my needs. I never thought I would spend $59,000 on a car. I purchased it in Arizona - much better than buying in Canada where it would cost over $70,000 and in Canadian dollars to boot. If I had only needed the old van for local use, I would have kept it a few more years but we need something dependable for lots of long trips.
