CarEdge Insights
Knowing which cars are most negotiable, and which command the highest price premiums, is a valuable piece of information for any car buyer. In 2026, knowledge truly is power. A critical piece of this knowledge is understanding the Market Day Supply (MDS).
MDS is a measure of the number of days it would take to sell all of a particular model of car, based on the current sales rate, assuming no additional inventory is added. A high MDS suggests an oversupply, potentially giving buyers leverage for negotiation, while a low MDS might indicate a seller’s market, where negotiating could prove tougher.
Using CarEdge Pro, we identified which new cars have the most and least inventory available in March 2026.
Why does inventory matter to car buyers?
Inventory influences negotiability. When there’s a glut of cars, dealers will be more inclined to negotiate with you. Slim pickings? Not so much. This valuable insight can give you an edge in your car buying journey, helping you save money and avoid the hassle.
