p.s. I bought a used Chrysler Town & Country lowered-floor Braun ramp van 2 1/2 years ago. I found it on the Internet in California, bought it from a private owner, had it shipped to Boston where I flew down from Newfoundland and took delivery and drove it home. It happened to come with hand controls which I didn't need at the time but now use daily. I am very pleased with it. It has a powered remote control driven ramp and side-door. My biggest problem was that it only had about 3 1/2" of clearance and I dragged it on curbs, driveways and snow. I solved the problem by buying big, 2" oversize SUV tires for it. I paid $15,000 US for it. I assume you live in Canada, Rhonda, and, if so, the dollar is now nearly at parity with its US counterpart so the American market for these vans is very attractive. Vans from the southern US are nearly rust-free and can provide good value. One caveat - if you are importing, ensure that the model you buy is cleared by the Canadian government for import. At the time I wanted to buy a Toyota Sienna rampvan but they were not authorized for importation. I believe they are now.
