To see which discontinued cars have been most popular lately, we looked at a full year of CarMax sales, from October 1, 2018 through September 30, 2019. The Jeep Patriot was our top-seller. The compact crossover SUV had a strong 11-year run, and thousands have been rolling off CarMax lots since production ended in 2017. The Chrysler 200 came in second among our best-sellers. The 200 was offered as a four-door sedan or two-door convertible from 2011 to 2014, then as a sedan from 2015 until it was discontinued in 2017.
