Just like last month, The Good Car Guy has tripled the amount of information in the United States Worst Selling Cars post. Scan the three tables below for America’s worst-selling vehicle by year-over-year decline. Then check out the list of mainstream participants (vehicles which haven’t yet been cancelled and remain displayed on their U.S. websites are eligible) which just don’t sell very often. Finally, there’s a list where all vehicles on sale today (and not yet cancelled) are qualified to form part of a list of the true worst-selling vehicles in America for August 2011.

The Good Car Guy doesn’t allow cars to be declared ineligible because they have good excuses. Every manufacturer has an excuse for why their product isn’t selling well, and most of those excuses are perfectly understandable. 

The Volkswagen Passat is only recently back on sale in America after skipping MY2011. The Chevrolet Sonic just began its new life replacing the Aveo – together they found 2876 buyers. The Hyundai Azera hasn’t really been cancelled but… the current model is dying and the new car just doesn’t seem to be able to make it across the Pacific. GoodCarBadCar.net has always displayed the Volvo S40 and V50 together. The V50 is mostly dead, however, and the S40’s 59% decline wasn’t as bad as the Toyota Yaris’s 61.655% drop. 

The Chevrolet Caprice hasn’t been made available to retail customers. The Saab 9-4X is a new offering from a genuinely screwed up automaker. Mazda pays about as much attention to the Tribute as the media pays to Rick Santorum. Rivals of the Lexus LFA don’t regularly release their sales data, so vehicles like the Lamborghini Aventador aren’t included alongside inevitably slow sellers like the LFA. You get the picture. There are reasons these vehicles are here.

The lists, however, forge ahead without asterisks. To give these vehicles an out would be to ignore what the vast majority of nameplates have been able to accomplish: escape the grasp of a Worst Sellers list.
