In the U.S., customer tastes in vehicles can shift unpredictably. In recent years, customers have preferred larger vehicles such as trucks, SUVs and cross-overs, leaving many models of sedans on languish on dealer lots for months. Other models of sedans remain popular, and tastes can shift off of certain models of SUV. One of the best ways to track consumer tastes is by determining the average number of days they take to sell.

24/7 Wall St. recently compiled a list of the average number of days each car model sat on a dealer’s lot before being sold in the U.S. market in 2018 (“days to turn”) based on data provided by Kelley Blue Book.

“Days to turn also can be a useful metric in determining which car segments and models are fading in popularity,” according to 24/7 Wall Street. “If a vehicle sits on the lot for six months, it often means the manufacturer overestimated how popular it would be.”

Following is a list of the 20 cars that averaged more than 130 days in 2018.
