Complex Says: To be fair, this isn't just unavailable in the U.S. It's unavailable anywhere. Alfa Romeo was set to put this car into production by the end of 2009, but troubled economic times led them to scrap it -- even though both Renault and Volkswagen have had remarkable success with sport-tuned hot hatches across Europe. We really wish they'd produce it, because then we could at least drive one if we took a European vacation.
