We don't know if anyone's ever called the Porsche Boxster the Beverly Hills Miata, but we're going to. It's maddening. The landscape of Los Angeles' richest suburb is littered with Boxsters. They're driven by soccer moms while their kids are with the nanny; by USC co-eds living off their parents' Amex Black card; and by movie agents yet to make the scene and jump to a 911 Cabriolet. It's enough to make you ignore the history of Porsche engineering and motorsports that this car's retro-style round face and plump bodywork are meant to evoke.
