You are going to get that in any new car, sans something really sporty. The average American is a fat ass. I know it would be tough, but see if you can find some seats from a jdm Fit/Jazz. They will fit better. When I had my old EG hatch, I swapped out the stock seats for a set of jdm eg6 seats. The cloth was better, and grippier, and the seats hugged me more.
