Part exchange my car

Get the best car trade value by comparing top offers from thousands of dealerships with carwow. Part-ex your car without fees or hidden costs.

What is part exchange?

Part exchange is when you partly pay for your new car with your old one. It makes changing cars clean and simple. You simply swap one car for the other. Drive to the dealer in your old car, drive away in the new one. Instead of paying the full amount for the new car, you pay the difference between the new price and the dealer’s offer for your old car.

This means you have to find less money to pay for the new car. Alternatively, the value of your old car reduces the amount you need to finance to put that shiny new model on your drive.

The big advantage of part exchange is that it makes the car-buying process easy and straightforward. The disadvantage is that you might be able to sell your old car for more privately or through a car-buying service.

You can part exchange through Carwow. The way we do things gives you the convenience of part exchange but without the disadvantages of part-exchanging through a dealer.

How much is my car worth for part exchange?

  • Make and model

    The specific model of your car will obviously be a huge factor - a Rolls-Royce is clearly worth more than a Ford Fiesta, while premium cars tend to depreciate less quickly than more mainstream models.

  • Age

    As cars get older, they tend to lose value. When you also factor in the speed of technological and engineering advances, and legislative changes to make certain types of vehicle obsolete or expensive to use, a car’s value can often decline even faster.

  • Mileage

    As a general rule of thumb, the more miles a car has travelled, the lower the value of the car. This is largely because high-mileage cars usually need more repairs and maintenance, which can be an expensive running cost.

  • Service history

    Has your car been serviced on time, every time? This is known as a ‘full service history’. If your car has been regularly serviced and you have the documents to prove it, this will increase your car’s part-exchange value. Main dealer rather than independent servicing helps with a car’s value, especially in its first few years on the road. It’s not so important when valuing older cars.

  • Condition

    Pristine bodywork free of dents and scratches, no sign of wear on the carpet and seats, fully functional electrics – all of these contribute to a car’s part-exchange value. The better the condition, the more the car is worth.

  • Paperwork

    Have all your paperwork in order – a taxed car with a valid MOT certificate is worth more than a similar car without. Make sure you also have your car’s registration certificate – called the V5C – to hand.

Why should I part exchange my car with Carwow?

Using Carwow to sell your old car broadens the market for it: instead of just being reliant on the dealer you're buying a new car from wanting your old one and offering you a good trade-in price, our comparison service will put your old vehicle in front of multiple dealers' eyes, meaning you get several bids, and can choose the best one.

Plus because the dealer who buys your old car will come and collect it from you at a time that's convenient, organising collection of your new car is a simple process, with none of the uncertainty surrounding timings that selling a car privately can bring.

Car trade and part exchange FAQs

If a second-hand car you're looking to buy is marketed as being a part-exchange car, this means the dealer bought it from another customer who bought a car through them.

If you are selling your old car to the dealer when buying a new car, your old car will be known as a part-exchange car.

Yes: trading in and part exchanging are used synonymously, and mean the same thing..
At a bare minimum you will need the registration document, technically known as the V5C, but informally called the logbook. If you've lost this it is possible to get a replacement from the DVLA, but you should obtain this prior to trying to sell your car or part exchange it.

Additionally, the more paperwork you have to do with your car the better. You should have the owners manual and service book (which dealers will stamp when the car has been in for maintenance). In an ideal world you will also have invoices and printed service records from these maintenance sessions, while if you have recently had new tyres fitted, or had the wheel alignment checked and adjusted, you should also include these. MOT records can be checked online, though it doesn't hurt to include paper copies of these, if you have them.

If your car is still in manufacturer warranty, also include the policy documents for this, and you should also be able to hand over both sets of keys, as well as any security tags to do with the car's locks, alarm or immobiliser system.

In short, the more proof you have that you have looked after your car, the better, and a car with a full, meticulous and documented service history can be worth significantly more than a car with none.

Potentially, yes, assuming the dealer you are part exchanging it with is aware of and happy with any issues.

How broken the car is will have some bearing on things, however: if the timing chain has snapped and wrecked the engine, you are unlikely to get much money in part exchange, whereas if the car just needs a new headlight bulb fitted, you should fare better.

In any instance, you could consider getting a quote to fix any faults with your old car, and weigh these costs up with any deduction the dealer would make for the issues when taking the car in part exchange.

You are likely to get a better price if you sell your car privately but in terms of convenience and logistics, part exchanging the car is more advantageous.
In theory this is entirely possible, though you would be best off having the conversation with an individual dealer. Assuming they are happy with this arrangement, they would sell you the new car, take your old car in part exchange, then transfer you the difference in price between the two cars in cash.
No, you cannot part exchange a leased car. Like renting a house, at no point during your leasing agreement will you actually own your car – it remains the property of the leasing company, even after your final payment. When your car leasing agreement has finished, you must return it to the leasing company.
Yes, you can part exchange a car on finance – provided there is no outstanding finance on the vehicle. Usually, you have the option to buy the car and own it outright when you reach the end of your finance deal. But you don’t have to wait until the end of your contract to get into a new car. We can offer you a valuation based on the market value of the car and will settle the outstanding finance on the car for you.

It’s then up to you how much of your part-exchange cash to put down on a deposit – you have that flexibility.
