Alfa Romeo 4C is a sexy, mid-engined Italian exotic carved down to affordable scale, and it's available as a coupe or with a targa top. Powered by a 237-hp turbo four and weighing less than 2500 pounds, its zippy power-to-weight ratio matches its zippy steering ratio; sadly, only a six-speed automatic is available. The 4C practically anticipates road challenges, but the seats are tight, there's almost no luggage room, and it's so low it's tough to get out of—none of which matters once behind the wheel.
