Somewhat discussed in this video on slowest selling and fastest selling cars/trucks. Guess what are the slowest for the most part? High priced cars and trucks. Slowest one is a Stellantis 3500 pickup. Based on how many are on dealer lots compared to how many were sold in the last 45 days, if Stellantis completely stopped making any, it'll take around 400 days just to sell what's out there. The 1500 isn't much better with over 300 days supply, same for Jeep Grand Wagoner and some other high end cars. Fastest sellers with almost no inventory are Kia Carnival, Toyota Corolla, etc.
More and more people are saying no to high priced vehicles.
