Selling a family car in the UK - everything you need to know

A good family car is more than just a set of wheels; it's what keeps you moving. From the school run and work commutes to weekend hobbies and UK staycations, it gets everyone where they need to go.

But when it's time to upgrade, the task of paperwork, pricing and preparation can quickly turn the process into a stressful chore.

That's why we've put together this handy guide, breaking the process down into bite-sized chunks to help you stay in the driving seat.

How to value your family car

When it comes to selling your car, you want to make sure you price it right. Anything too low could mean you risk losing money, while a high price may make it impossible to sell.

You can look at similar models advertised on dealership websites or private classified adverts. Note how long a car has been listed for sale, as the ones that linger for a while are likely overpriced. 

Remember that two cars of the same model can still have different values based on a number of factors, including their mileage, service history, MOT inspection, tyre condition, interior wear or number of previous owners.

Car marketplace Autotrader offers a free valuation. In fact, Autotrader has their Mumsnet Rated Valuations Tool, which 91% of 63 Mumsnet testers recommend using. The tool compares millions of models and live market data to give you the most accurate valuation and you can get results in under ten seconds.

Erin Baker, auto expert, says: "Selling the family car can be surprisingly emotional. Given how much time we all spend bonding/arguing in them, plus treating them like an extension of the household bin, it can be tough to let them go. But when it's time to say goodbye, don't get emotionally attached to your selling price. 

“Be realistic: see what the same model of similar age and mileage is going for on Autotrader or use the free valuations tool which will get you a valuation in under 10 seconds. Also, take good photos - spend time and thought on location and lighting, if you want to sell quickly and for a good price."

What documents do I need to sell my family car?

You can sell your car in the UK without the relevant paperwork, but it will likely make the whole process much more complicated, knock money off the price and potentially put buyers off making an offer.

1. V5C logbook and service history

The V5C logbook will officially record the change of ownership. How you fill it out depends on who you're selling with. Sell privately and you'll need to complete sections 2 and 6. With a dealer, you'll typically fill out section 4 and the dealer will handle the rest.

Until the DVLA confirms the transfer, you remain responsible for the vehicle, including any fines or penalties. A change of ownership is really important.

Offering the buyer the car's full service history will increase the car's value. It'll give buyers confidence regarding the car's history and help to build trust ahead of a sale.

2. A valid MOT 

A valid MOT shows that your car is safe and roadworthy, so this is a must, especially for any vehicle over three years old. Buyers will be expecting a valid MOT so they can check for any outstanding issues that could cost them down the line. MOT checks can be found online, but keeping printed copies or receipts for any suggested work could be helpful for a buyer.

3. Repair documents (if applicable)

If you've made a claim on your car, it's a good idea to provide buyers with the repair documents. This shows the necessary work has been done and reassures them that you're being upfront about the car's history. Make sure to contact your insurer once the sale has gone through to cancel your policy.

Having all your paperwork in order will make the sale process much smoother

How to prep your car for sale

There are various things you can do to help prepare your car for sale. It's important to make sure your car is in good working order. If you have less than six months left on the MOT, it's always a good idea to get a new test to identify any issues.

When it comes to minor things, like scratches or signs of wear and tear, it's important to weigh up whether it's worth fixing before selling. Buyers may not be put off but they will expect a lower price for cosmetic imperfections. If you're selling an expensive model that's fairly new, it might be worth spending a little to repair things so you can sell it for the best price.

Just like with a house, a clean and well-presented model is much more attractive to buyers. In fact, research from Autotrader shows that more than three quarters of buyers agree that a clean car suggests the owner has looked after it mechanically. Nine in ten car buyers say poor presentation would stop them paying full price for a mechanically sound vehicle, with nearly 70% expecting at least 6% off the asking price for a scruffy looking car. 

Even if interiors are worn, give everything a good vacuum and clean the upholstery with a strong cleaning product to make a big difference. Make sure the windows are clean and sparkling and clear the boot to showcase its full potential. The effort is worth it - 75% of buyers say they would pay more for a well-presented car compared to a scruffy one. 

Where should you sell your car? 

You can either sell your car privately or go through a dealer and there are pros and cons to both. Selling your car privately usually means you'll get a higher price, as you'll deal directly with buyers and won't have to pay a dealer any commission.

Autotrader not only offers an instant valuation, but it also has more potential buyers than any other site for an easy private sale. 

Mumsnet testers liked being able to see these options side by side before committing:

“I like that it shows you what you’re likely to get from a dealer, part exchange or selling privately – it helps you decide what’s actually worth the hassle.”

Others said this clarity helped them rethink automatic part exchange:

“It’s made me consider options other than just part exchange at a dealership.”

Autotrader also gives you the option to sell via auction to dealers, where you can access a network of trusted dealers easily who may want to put in a bid for your car. This is a great way to sell your car if you’re time poor. Plus, they also offer the option of a part exchange, which is when you sell your car and use the value towards the purchase of a new vehicle.

Selling privately does mean you'll have to handle all the admin, organising the advert, the viewings, negotiations and paperwork. So it depends on whether you want the best price or the easiest sale.

When is the best time to sell a car?

A good family car is essential year-round, but there are a few things that might contribute to a quicker sale at different times of the year.

Buyers may focus on newer cars around March and September, which is when the new registration plates are released. As a result, demand for used cars may dip.

The seasons can also impact the type of car people are searching for. During the warmer months, things like convertibles and classic sports cars become much more attractive. But in autumn and winter, people may be more swayed by SUVs, off-roaders and 4x4s.

Choosing between a private sale and a dealership depends on your priorities

Do I need to inform the DVLA when selling my family car?

Yes, as this transfers the ownership of the vehicle to the buyer. Just complete the relevant sections of the V5C logbook or do the transfer online. There are different sections to fill out depending on whether you're selling via a dealer or privately.

How long does it take to sell a family car?

There's no exact timeline for selling a car, but a well-maintained vehicle and a fair price usually sell faster. If you're after a fast sale, consider pricing lower or going through a dealer, who can agree on a same-day sale and handle all the relevant paperwork.

What happens after I sell my family car?

With a dealer, the process is fairly simple as they will handle the paperwork, notify the DVLA and take the V5C logbook and submit the ownership transfer for you.

With a private sale, you'll need to handle all of those things yourself and be sure to keep a receipt of sale for your own records. Clear the car of any personal belongings and always remember to cancel the insurance policy.
