Does the mazda 6 seat fit in the 3? If I drive more than an hour my back is killing me. I have tried the lumbar in all positions and I just can't seem to make it work for me. I knew the seats weren't GREAT when I bought the car. I would have put them with my SER in initial comfort. But now that I have the car a one hour trip is a pain in the back. Any suggestions? Any after market seats that don't look like they belong in a race car or cost half of what I paid for the car?
