Infiniti has grown tremendously since its debut and has recently gone global, with its G series of vehicles leading the charge. So to properly honor its birthday milestone while simultaneously paying homage to its favorite model, Infiniti has built a limited run of the G37, simply labeled the G37 20th Anniversary Edition. Only 350 anniversary-spec sedans (rear-wheel and all-wheel drive) will hit dealers this model year. Opt for a coupe, or a snazzy hard top convertible, and your pickings are slimmer. Just 200 of each are currently being delivered straight from Nissan's Tochigi plant.

Exactly what's so special about the special edition models? First off, the limited run guarantees you'll have a little piece of Infiniti history. (For reference, in the first five months of 2010, a total of 22,430 G37s were sold in the U.S.)
