My Mazda5 Sport is a beautiful van. Sleek and not boxy like so many vans. Handles like a car and not a truck. The intown mileage is around 21-22 mpg which is important this day and age. I haven't taken it on a long trip yet but will in the future. I am just so very pleased with my new car!!
I had a 2012 M-5 as a work vehicle, covering a large territory servicing equipment. I folded down the 3rd row seats, removed one of the middle row seats, and built a shelf to hold parts & tools. I loved the sliding doors on both sides. The trunk hatch might be an issue for someone taller (I'm 5'7").
It was comfortable and fun to drive for several hours a day, good acceleration on the freeway (even when somewhat full of stuff). Good visibility, and enough zip to it to still be fun.
