Although I still drive my 96 Windstar daily for work (229,000 miles) the Flex is for weekend and pleasure use for now. Ford has outdone themselves and can compete with the imports with the Flex. The ride is exceptional and the interior room is huge. I am averaging about 25.5 mpg on the road. I do not live in a congested area so gas mileage should be good for me.
The overall handling, the sound system and the vista roof are favorites along with the lighting package offered.
A front sonar sensor similar to the rear would be helpful with such a long front end.
