Mazda does a pretty good job of keeping their production cars fairly similar to the concepts...look at the concepts for the previous 3, and the current gen 3. The nagre influence is very clear in all their current models...though not so much the 6. I can see it in the 2, the 3, the new 5yeah, saw this the other day (on tumblr, lol). i freaking love it.
let's all keep in mind that production cars never look exactly like their concept counterparts though.
