Well, that one guy may think the changes to the new vehicle don't matter, but I disagree. There are other things besides test track numbers, ya know. Having gotten used to the push button start on my Mini, I would really love it on the Mazda. A memory driver's seat is very nice. I love being able to just push a button and everything is just right again after my wife, mechanic, etc. has driven it. Did he say he cranked the seat heater up to level 5? Sounds a whole lot better than the current on/off choice. Dual zone a/c? Sure beats single zone. And the navigation. Sure the screen looks smaller than usual for a built in, but it really looks built-in instead of bolted on. I really did not like the on top of the dash, pop-up nav on the current 3, especially because the screen is way up there while the controls are way down on the center console. Nav controls on the steering wheel! Cool. So, even if the perfromance isn't noticeably different, I'd hardly say the changes to the 2010 3 don't matter.
