Buick shows Regal sedan at Los Angeles Auto Show

Buick has finally shown its Regal in the US, as a 2011 model at the Los Angeles Auto Show.
   Built in Germany, the Regal is essentially a badge-engineered Opel Insignia, which was the European Car of the Year for 2009. A softly sprung version of the same car is already in sale in China.
   The US gets the Regal with 2·0-litre turbocharged and 2·4-litre engines.
