Part exchange value
Also known as: PX value, part-ex
Part exchange value is the amount a dealer offers against a customer's existing vehicle when they buy a new one - usually equal to or slightly below the trade valuation.
When a customer trades in their existing car against a new purchase, the dealer offers a "part exchange" (PX) value. This is essentially a trade purchase: the dealer expects to either re-sell the trade-in vehicle on their own forecourt at retail, or send it to auction for a quick turnaround.
A part-exchange offer is typically 0 to 10% below pure trade valuation, reflecting the additional cost the dealer takes on to handle the trade-in: reconditioning, MOT, valet, finance settlement on any outstanding agreement, and the holding cost while the vehicle re-sells.
Customers can use DealerPricing's trade valuation tool to know what a fair PX offer looks like before walking into a dealer. Knowing the underlying trade price typically gains £200 to £800 in negotiation against the first offer.
