Part Exchange (PX)
A part exchange (PX) is when a customer trades in their current vehicle as partial payment toward a vehicle they are buying from a dealer.
Part exchange lets a customer roll the value of their old car straight into the deal on a new one, rather than selling it separately first. For the dealer, the PX vehicle itself becomes new stock, which is why appraisal accuracy matters so much.
How it works in a deal
- The PX vehicle is appraised and a trade value agreed with the customer
- That value is offset against the price of the vehicle being purchased
- Any outstanding finance on the PX vehicle is settled before the deal completes
- The PX vehicle enters the dealer's own stock to be prepped and resold (or sent to auction)
Where this connects to other DMS functions
A part exchange touches deal building, vehicle appraisal, finance settlement, and stock management all in one transaction — which is exactly why a DMS that handles all of these in one place avoids the re-keying that happens when they live in separate tools.
