The following cars and trucks represent the 10 models identified by TrueCar.com as being in greatest supply on dealers’ lots. Cars and trucks that sit for longer periods in inventory cost a dealer more in financing costs than faster-selling models. Thus dealers have an added impetus to sell overstocked vehicles at deeper-than-average discounts. For each model we note the number of average days in inventory (48 is average) and applicable factory sales incentives, including cash rebates, financing deals and additional discounts paid directly to a dealer that can be applied to the transaction price. We’re also including the range of list and invoice prices to help identify the amount of dealer markup that’s up for negotiation.
