2011 Porsche Cayman R Green
Porsche Cayman R

Factored out three ways, these were America’s worst-selling cars in December 2011. Numerous cars in the first list of Worst Sellers By Percentage Decline create no surprise by their presence. 

The Saab 9-3 and 9-5 come from a company that’s mostly/definitely/completely/probably dead. The two Lexus sedans and two Acuras make frequent appearances here. 

In the light of the better-in-almost-every-way Kia Soul, the Nissan Cube is proving to be less and less desirable. Meanwhile, most Mercedes-Benz CL-Class customers would veer towards the SLS AMG or the newer BMW 6-Series.

In the second list, one which groups non-premium cars (a hard to define category) by volume, the barely-marketed Hyundai Azera and Suzuki Equator present themselves as likely candidates every month. The Mitsubishi i MiEV and Chevrolet Caprice PPV stand little chance of escaping. Scion’s iQ is brand new to market, so is the Buick Verano.

The third list takes into account vehicle of all types and groups them by volume. Here, the ultra-exclusive Lexus LFA stands no chance of escaping top spot. The 9-4X takes over from Saab’s 9-3 and 9-5. Apart from the fast-declining Porsche Boxster and Cayman, most cars here either belong or, because of their niche status, will always struggle to escape worst seller status.

Last month’s version of this American worst-selling cars post is here. The more exciting 2011 year end results are up now, as well.
