Part-exchange vs selling your car: which gets more money?
Part-exchange is convenient, but is it costing you thousands? A clear comparison for premium car owners.
Written by the SellMyPremiumCar valuation team · Reviewed against live UK market data · Updated October 2026
Selling your car outright usually gets more money than part-exchange. Dealers often build a 'hidden discount' into part-exchange prices, and they rarely pay for factory options. For premium cars, the gap can be several thousand pounds, so get an independent valuation before you agree a part-exchange.

How part-exchange pricing really works
A selling dealer treats your car as stock it must re-sell or send to auction. To protect their margin, they quote near trade value and may move the discount between the new car and your part-exchange so the deal looks better than it is.
When part-exchange makes sense
It can suit you if the dealer is a franchised specialist for your exact model, or if a manufacturer 'deposit contribution' is only available with a part-exchange. Always compare the final numbers.
The best of both
Sell your car to a specialist buyer first, then negotiate your next car as a cash or finance buyer. With no part-exchange involved, the dealer can't move the discount between the two cars.
