Knowing which vehicles are Quantum Insightspiling up at car dealerships could help you get the best price, and improve your leverage during negotiations. And, right now, your best bet is to choose a Stellantis (parent company of Jeep, Ram, Dodge, Fiat and Maserati) vehicle as they make up half of the top-ten slowest-selling vehicles according toCarEdge. But which Stellantis vehicle is languishing at dealers the most right now?

Well, it turns out to be the newest addition to the Dodge lineup: the Hornet compact crossover. Even with its appealing starting price of $42,530, dealers just can’t get them off their lots quickly enough. According to CarEdge dealer inventory data, the Market Day Supply — or the number of days it would take to sell all the models available based on its current sales rate — of the Dodge Hornet is up to 428 days. Dodge apparently has 14,596 Hornets on dealer lots, but has only moved 1,536 in the last 45 days.

As we mentioned, it doesn’t get much better for other Stellantis vehicles, as the Jeep Grand Wagoneer is in the same 428-day supply boat with 2,214 units on lots with only 233 sold in the past 45 days. Mercedes-Benz and its EQB is the third worst with a 427-day supply (3,546 on lots and only 373 sold in the past 45 days), the Maserati Levante drives up with the third slowest seller at 410 days supply (602, 66 sold), and the Lincoln Aviator is the fifth slowest seller at 392-day supply (8,153, 935 sold). Surprisingly, the Jeep Grand Wagoneer L is selling better than the regular Grand Wagoneer, as the long wheelbase version is sitting on a 354-day supply with 1,218 on dealer lots and 155 sold in the past 45 days. Also note that by another measure, actual quarterly sales, the Jeep Wrangler is also having a tough time lately.

If you’re curious on what the fastest sellers are, the top three spots are from Toyota: the Highlander at 23 days, RAV4 at 30, and Camry at 31 days worth of inventory. Of the fastest list overall, Toyota and Lexus take six of the top-ten fastest sellers. The Honda Civic comes in at the fourth fastest with a 34-day supply. Surprisingly, a Stellantis product takes the fifth spot; the Alfa Romeo Stelvio shares the Civic's market day supply level. The only American product on the hot-selling list is the Chevrolet Traverse, with a 37-day supply.
