I want to start by saying something that might surprise you coming from a company that buys non-runner cars: selling privately isn't automatically the wrong choice. If you have a car that's broken down but is otherwise clean, popular, and the fault is something a mechanically minded buyer can fix cheaply, you can sometimes get a reasonable private sale price. It happens.
But for most non-runner owners, and I mean the vast majority of the people who contact us, private sale either fails entirely or ends in a worse outcome than if they'd come to a specialist first. Not because private buyers are dishonest, but because of a set of very specific, very predictable problems that come up every time you try to sell a car that doesn't run through the usual channels.
I've heard these stories so many times that I could write them from memory. Here's what actually tends to happen.
Problem One: The Buyer Pool Shrinks to Almost Nothing
When you list a running car privately, you're selling to essentially the entire used car market — private buyers, enthusiasts, first-time car owners, people who just need something to get to work. When you list a non-runner, you're selling to a very specific and very small group: people who can diagnose and repair the fault themselves, who have the tools and space to do it, and who are also willing to arrange their own recovery transport to get the car home.
That's a small group at the best of times. On Facebook Marketplace, which is where most private non-runner sales are attempted - it gets smaller still. The platform is well known for attracting casual browsers and non-serious buyers even for straightforward running cars.</cite> For a non-runner, you're waiting for a very specific needle in a very large haystack of people who message asking "what's wrong with it?" and then never respond again.
On AutoTrader, you'll reach more serious buyers, but the platform is designed around running vehicles with HPI checks, service history, and the ability to arrange a test drive. A non-runner listed there tends to get very little traction and sits for weeks at a price most owners eventually have to reduce.
Problem Two: Recovery Transport Is the Buyer's Problem, and They Know It
This is the one that catches people off guard most often. When a car won't start or drive, it can't be collected like a normal private sale. A buyer can't just drive over, hand you cash, and drive it home. They have to arrange and pay for a recovery truck or trailer to come and collect it - and that typically costs £80–£250 depending on distance, or more if the car won't roll and needs a winch.
In my experience, the moment a private buyer starts factoring that cost into the deal, one of two things happens. Either they walk away because they hadn't budgeted for it, or they come back and want to reduce the agreed price by at least that amount - sometimes more, to account for the inconvenience. A buyer who was happy to pay £1,200 for the car suddenly wants to pay £900 once they've priced up recovery. And that's before they've had a look at it in person.
Problem Three: The Inspection Drop-Off
Here's a pattern I hear about constantly. Owner lists non-runner for £X. Buyer expresses interest, messages enthusiastically, says they can fix the problem. Owner spends a few days going back and forth with details, photos, possibly getting the car partially inspected. Buyer comes to look at it. Buyer sees it in person and either spots something they hadn't anticipated, decides the job is bigger than they thought, or simply gets cold feet now the reality is in front of them. Buyer offers significantly less. Owner, who has now spent a week on this, either accepts a lower price or loses the sale entirely and has to start again.
This isn't the buyer being dishonest. It's just the nature of buying a car with an unknown or partially known fault -the uncertainty multiplies when you're standing in front of it. Even when parts are unaffected by a mechanical failure, buyers find it hard to be confident about what they're taking on when the car isn't running. A specialist buyer like us does this every day and can price that uncertainty professionally. A private buyer with no experience of the specific fault type tends to get nervous and offer less.
Problem Four: Cash Buyers Want a Discount That Makes the Maths Work Against You
Private sale buyers who are serious about non-runners are almost always cash buyers, usually people who buy, repair, and resell. They're experienced, they know what recovery costs, they know what the repair costs, and they know what they can sell the car for once it's fixed. They will offer you a price that works for their business model, which means their margin, their repair cost, their recovery cost, and their risk premium all come out of your price.
There's nothing wrong with this - it's how business works. But it often means the cash buyer's offer is not much better than, and sometimes lower than, what a specialist buyer like us would pay. The difference is that the cash buyer also wants you to deal with the uncertainty, the waiting, the time-wasters before them, and the logistics of getting the car to them somehow.
Problem Five: Outstanding Finance Complicates Everything
If there's any outstanding finance on the car, private sale becomes significantly more complicated. Legally, you can't sell a car with finance outstanding without settling it first or making arrangements - a private buyer who discovers undisclosed finance after the sale has recourse against you. That means you either need to settle the finance out of your own pocket before the sale, or find a private buyer who is willing to wait while you arrange a settlement.
Most private buyers aren't willing to wait. We handle this routinely - we contact the finance company directly, arrange the settlement, and pay you the difference. It's a standard part of the process for us and a significant complication for a private sale.
When Private Sale Is Worth Trying
I said at the start I'd be honest, so here's the honest version: private sale can work in a narrow set of circumstances.
- The fault is minor and clearly diagnosed - a dead battery, a faulty sensor, a known cheap fix
- The car is a popular model in genuine demand - something with a large enthusiast community or high parts demand
- You have the time and patience to wait for the right buyer
- The car is still partially driveable, which removes the recovery problem for the buyer
- You don't have outstanding finance to deal with
If most of those boxes are ticked, listing privately first costs you nothing but time, and you might do better than a specialist offer. Go for it.
If the fault is serious, the car is fully immobile, there's finance on it, or you've already tried the private route and hit the problems above, a specialist buyer is almost certainly the more straightforward route to more money with less hassle.
What the Alternative Actually Looks Like
At Sell The Car, the process for a non-runner takes about two minutes online. You enter the registration, tell us whether it starts, describe the fault roughly, and we come back with an offer - usually immediately. If you accept, we arrange collection from anywhere in the UK using our own recovery transport, and we pay you before the car is collected. No viewings, no time-wasters, no renegotiation on collection day, no waiting for a buyer who said they'd come on Saturday and didn't show up.
I'm not saying that to be self-promotional. I'm saying it because the contrast with what I've described above is relevant if you're deciding what to do next.
If you want to see what we'd offer before you decide which route to take, enter your registration number on our sell a non-runner car page for a free, no-obligation valuation. You can also read more about selling a broken car whatever the fault type.
There's no commitment, no pressure, and no charge. And at least you'll have a number to compare against whatever else you try.
FAQs
Can I sell a non-runner car on Facebook Marketplace?
Yes, you can list it — there's no restriction. But in practice, non-runners attract a narrow pool of serious buyers on any platform, and the logistics of collection (the buyer needs to arrange and pay for recovery) often causes deals to fall through or prices to drop significantly. It's worth trying if the fault is minor and the car is otherwise in good condition, but it takes longer and involves more uncertainty than most owners expect.
What's the best way to sell a non-runner car privately?
Be precise about the fault in your listing rather than vague - serious buyers want to know exactly what's wrong so they can assess the repair cost and decide if it's worth their time. Include clear photos of the car, the fault warning lights or damage, and the interior condition. Price it honestly relative to the car's value minus repair cost and recovery cost. And be prepared for the pool of genuine buyers to be small.
Is it worth repairing a non-runner before selling privately? Only if the repair is inexpensive relative to what it adds back to the sale price. A £200 repair on a car you can then sell for £1,200 instead of £500 as a non-runner is worth doing. A £1,500 repair on a car that will sell for £1,800 running but £800 as a non-runner is not - you'd spend £1,500 to gain £1,000.
Do I have to disclose a fault when selling privately? Yes. When selling privately in the UK, you're obliged to accurately describe the car's condition. Knowingly withholding a fault - particularly one affecting roadworthiness - can result in the buyer pursuing a claim against you after the sale. A specialist buyer already factors the fault into their offer, so disclosure is built into the process from the start.
