Amanda has that problem in all Mazdas. The MS6 is a little better than the P5 but when she test drove the 2, 3, and 5 she felt it immediately.Edit: I drove a 2012 Mazda 6 as a rental once. I loved it except it has the same seat problem my MS6 has... I get lower back pain after a few hours. Other than that, the car was just a blast to drive and such.
