A Fusion ST.
Same engine as the Focus ST, but maybe making an extra 10-12 hp. All-wheel drive. Adaptable suspension. Manual 6-speed. Recaros, but more subdued than the Focus'. Slightly more aggressive styling, but nothing too ostentatious.
I know it'll never happen, with the Mazdaspeed6 as the precedent and ballbuster. Still, a guy can hope for a reasonably quick, relatively inexpensive, relatively good looking sport sedan that a dad wouldn't feel like a dork for driving.
