Most of us celebrate our birthday with a cake and some booze. Honda, for its 50th, one-upped the party by building a car. And not just any car, but the convertible S2000. With its buff cross frame, small 2.0-liter, high output 237 hp motor, the balanced Honda was lauded by journalists as the most balanced object since the weighing scale or California's budget. Well maybe not so much the latter, but you get the idea. Happy belated, Honda.
