When the city of London decided in November 2006 to tax gas-guzzling, emission-spewing vehicles (aka sports cars), we knew someone would put up a fight. It didn't take long before Porsche, the enthusiast-oriented German automaker, stepped into the ring. Round One started last month, after London's Mayor Ken Livingstone decreed that a $50 daily tax shall be levied against all environmentally unfriendly vehicles that drive through his city beginning this October. After Porsche formally requested the mayor reconsider his plan or else it would call for a judicial review of the proposal, the Mayor kicked off Round 2 by accusing Porsche of imposing unnecessary pollution on Londoners and then compared the brand's sports cars to garbage littered on the street.
