????6.別克君威

????降38%

????這款車本應成為暢銷車的有力競爭者,。繼在中國市場獲得成功后又在美國重新推出,，富貴典雅的君威一直受到定價高、包裝差和可靠性低于平均水平的困擾,，同時還遭遇了別克其他車型的同門競爭,。

????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.
