Knowing how many of a particular model of car that dealerships around the United States have in stock can be a powerfuKnowing how many of a particular model of car that dealerships around the United States have in stock can be a powerful tool to keep in your pocket when it comes time to negotiate a new vehicle’s purchase price.The more of any single model of car that are languishing unsold on dealer lots around the country, the more likely that dealers will negotiate a better price to make a sale. On the other side, cars that are more difficult to find on showroom floors near you aren’t likely to be sold at a discount. There are other factors at play—one of which is the continual threat of further tariffs—but stocking levels are useful nonetheless.CarEdge, a company that uses its internal data to help buyers make smart purchase decisions, compiled a list of the cars that take the longest and shortest periods before they sell. The data is presented in a Market Day Supply (MDS) report that lists the number of days it would take to sell the entire inventory of a particular car model based on the current rate of sales and assuming no additional inventory is added.New Cars With The Highest Inventory Levels in June 2025:Ram 2500: 392 MDSAudi Q4 e-tron: 399 MDSAudi A6: 368 MDSVolkswagen ID.4: 262 MDSJaguar F-Pace: 243 MDSLand Rover Range Rover Velar: 241 MDSPorsche Taycan: 241 MDSAlfa Romeo Stelvio: 218 MDSAudi A8: 217 MDSLand Rover Discovery: 209 MDSslowest selling cars of 2025 so farBefore you go over to your local dealer looking for a smoking deal on a new European luxury car, you should keep in mind that some of what looks to be an overstock of vehicles may be the result of these automakers shipping cars to the United States in advance of potential Tariffs. Similarly, the Ram 2500 that sits at the top of the MDS list is assembled in Mexico, which, although Trump negotiated the United States-Mexico-Canada Agreement (USMCA) in his first term, is also threatened by tariffs.With so much uncertainty surrounding what tariffs will or won’t be charged to automakers and passed onto paying customers, it’s harder than ever to determine when the best time to buy a new car or truck is. At least if you’re armed with this knowledge of Market Day Supply numbers, you have an idea of how aggressive you could potentially be when negotiating the out-the-door price with a dealer.
