The 100 Worst Cars in America in 2013 offers a list of the worst cars and trucks available in the U.S. It uses AutoOnInfo.net’s Overall Reliability GPA covering model years 2003 to 2012 for ranking pickup trucks, sport-utility vehicles (SUVs), minivans, family cars, wagons, small cars, hatchbacks, sport/sporty cars, coupes, convertibles, upscale cars, and luxury cars in order to aid consumers in avoiding a vehicle that may require a larger number of repairs and a greater number of expensive repairs. To this end, it includes each car’s reliability GPA and grade and the number of model years upon which the GPA and grade are based, as well as brand and manufacturer GPAs for comparison and contrast and for better assessing long term performance and ownership expenses. Also, near the end of the book are a chapter listing the next 25 worst cars (31 by tie), with GPAs and number of model years, and chapters giving brand and manufacturer shares of the 125 (131 by tie) Cars in America in 2013.
