A fair part-exchange offer is based on your car's condition, its service history, what similar cars are selling for now, the work needed before it can be resold, and any finance still owed. Bring your paperwork, be upfront about known faults, and expect the final figure to be confirmed once the car has been seen.

What is part exchange?

Part exchange means selling your current car to the dealer you are buying from, in the same deal. The value of your car, minus any finance still owed on it, comes off the price of the car you are buying.

You do not have to buy to sell. If you just want to sell your car, start at sell your motor. If you want to see what you could move into, browse cars in stock.

How is a part-exchange value worked out?

Five things shape the figure. Leave one out and the number will not hold up.

Condition

Bodywork, tyres, brakes, warning lights, interior wear, damp, and how the gearbox and clutch behave on a drive. Stone chips are normal on a used car. Rust on sills or arches, a slipping clutch or a warning light on the dash are not cosmetic.

Service history

Dated invoices that show the mileage, the work done and the garage are the strongest evidence. Stamps in a book help, but invoices carry more weight. Gaps are not a disaster if you can explain them. Our service history guide covers what a buyer looks for.

What similar cars are selling for now

The value reflects current prices for cars of a similar age, mileage and condition, not an old screenshot or the most optimistic private advert you have seen.

Work needed before resale

If the car needs tyres, a service, brake work or a body repair before it can be sold on, that cost is taken into account. Someone has to pay for it before the next owner gets the keys.

Outstanding finance

If you still owe money on the car, ask your lender for a settlement figure. It changes daily as interest is added, so get a fresh one close to the deal. Any value left after settling the finance is your equity. If you owe more than the car is worth, that shortfall has to be dealt with as part of the deal.

What should I bring to get an accurate figure?

The V5C log book in your name
The service book and any invoices
All keys, the locking wheel nut key, and charging cables if the car is a plug-in hybrid or electric
A current finance settlement figure if anything is still owed
A note of any faults you know about

It also helps to look up the car's MOT history on GOV.UK before you go. Any buyer will check it, and it is better to know what the advisories say in advance.

What pushes a value up or down?

Usually helps:

Full, dated history that matches the MOT mileage
Good tyres, sound brakes and no warning lights
Two keys and a clean, dry interior
A colour and specification that buyers want
A clear finance position

Usually reduces the figure:

Long gaps in the history
Clutch, gearbox or steering problems
MOT advisories that have not been fixed
A missing key, locking wheel nut key or charging cable
Bodywork that needs repair

Should I sell privately instead?

A private sale can sometimes bring a higher headline price, but you take on the viewings, the haggling, the risk around payment and the time it takes. Part exchange is quicker and keeps everything in one transaction. Our guide to private sale versus selling to a dealer sets out the trade-offs.

Can I use finance for the car I am buying?

Yes. Your part-exchange equity can act as some or all of your deposit. We are a credit broker, not a lender. We work with a panel of lenders, and any finance is subject to status and affordability checks. We receive a commission from the lender for arranging finance and we disclose this; if you would like to know how much, just ask. You can start a finance enquiry here.

Common questions

Can I get a part-exchange value without choosing a car first?

Yes. You can ask for a valuation or sell outright through sell your motor. Any figure given before the car has been seen is an estimate. The final offer depends on the car on the day.

What if I owe more than the car is worth?

That is negative equity. You can pay the difference, or in some cases it can be included in new finance, subject to status and affordability checks. Adding it to new borrowing means paying interest on it, so think carefully first.

Can I part exchange an electric or plug-in hybrid car?

Yes. The same rules apply, with a few extra checks: the charging port, the cables, and how the battery and range are behaving.
