Hi, I am 71 & have had back surgery & have driven toyotas for25 years. Purchased a 2007 Prius in May of 2007. I live in Minnesota, drove to colo. the last of feb. A total of 2,732 miles. Averaged 45 miles per gal for the complete trip. 61 gal of gas. I find the seat very comfortable for me. I am 6 ft tall. My wife had a new hip & both knees replaced in April of 2007. She was very apprenhensive about this trip. It went well. Have no complaints about the seats. Very good on the back.
