Don't know how to edit on this board...
I think there is a market for a new MX6, though. But it would have to be more true to it's "roots" rather than just chopping a door off the current 6. The MX6s worth a shit were always a little bigger than the main competition, and somewhat ended up being in their own "class" because of it. But, they offered more power than what you would compare them to, and usually longer/lower/sleeker styling.
With Mazda focusing on taking weight out of their cars (R3 RX8, next iteration of MX5), i don't think it'd be hard for them to make a ~2700lb car and stick a nice smallish V6 in there making 200-225hp. Take the 6, shrink it maybe... 20%, chop the roof, extend it a little further back to almost but not quite mimic a fastback, offer a 6spd manual, 17" wheels, big-ish brakes all around, and people would come. Civic Si for people who hate the styling, and want a bigger, smoother powerband.
