GM to build Cadillacs outside the U.S.

General Motors CEO Dan Akerson said Tuesday that the company plans to begin building Cadillacs outside the United States by the end of 2012 as part of its plan to make GM's premium brand a true global nameplate. Akerson said overseas Cadillac production would reduce the risk of foreign-currency fluctuations and allow GM to better manage its supply chain.

Aston Martin V12 Zagato: First production car photos

Ahead of a debut in Kuwait in two weeks, we have the first official photos – interior and exterior – of the production version of the Aston Martin V12 Zagato.  So far we’ve had just one outside picture of the production version of the Aston Martin V12 Zagato, and we know that it will make its production debut at the Kuwait Concours d’Elegance on 15th February. But now we’ve got more pictures. Aston Martin has quietly published a PDF on the V12 Zagato (link to Aston Martin V12 Zagato PDF) which gives us some of the history behind the development of the V12 Zagato, tells us how it’s made (with craftsmen and hammers) and, for the first time, gives us a look at bothy the inside and outside of the new Zagato.
