That is very nice that the vehicles work for you.
I, on the other hand can only get in and out of their Windstar/Freestars and am deeply disappointed they no longer make them. The Flex wouldn't work and the Econoline is way too big.
I have an electric wheelchair that fits perfectly in the back of my Windstar with a lift.
The flat floor makes it easy for me to get in the sliding door sides. I do not drive.
