Found this in an article about limousines for marriage. Between the obvious offerings from Benz and Audi this Buick Century limousine stands out. The Century was made in China by Shanghai-GM and was later replaced by the almost identical Buick Regal. The current China-made Buick Regal is no more than a rebadged Opel Insigina. The limo is stretched by at least two meters, the conversion likely done in China.
