????6.别克君威

????降38%

????这款车本应成为畅销车的有力竞争者。继在中国市场获得成功后又在美国重新推出，富贵典雅的君威一直受到定价高、包装差和可靠性低于平均水平的困扰，同时还遭遇了别克其他车型的同门竞争。

????6. Buick Regal

????Down 38%

????It should have been a contender. Reintroduced to the U.S after a successful run in China, the stately Regal has been hurt by its high price, poor packaging, and below-average reliability -- as well as cannibalization by other Buicks.
