Selling a car with engine or gearbox damage
A blown engine feels like a total loss. It rarely is. I explain what your car is still worth despite the fault, and when repairing no longer makes sense.

A blown engine doesn't make the car worthless
Almost every week, someone rolls up with a car that won't start properly or just rattles when it tries to move. And almost every time I hear the same line: it's only scrap now. It rarely is. A car isn't a single part, it's a few thousand of them. If the engine is gone, that doesn't mean the body, the gearbox, the interior, the electronics, the wheels or the catalytic converter are gone. Those are exactly the parts that have a market. On top of that, a professional buyer does the maths differently than a private person: we have our own workshop logistics, access to cheap replacement parts and buyers at home and abroad. That's why we can almost always pay more than the bare scrap price.
What a broken car is still good for
Why is a broken-down car worth anything to us? There are basically three routes, and the inspection usually decides which one. - Parts donor: doors, seats, control units, gearbox, axles, headlights — good used parts are in demand and sold individually. - Sensible repair: we get replacement engines and gearboxes far cheaper than a private customer and fix the car in our own workshop. Afterwards it's a normal used car again. - Export: in some countries repairs are so much cheaper that transport pays off. A car written off here still drives elsewhere. Which route is right depends on make, age, model and the type of damage. For you as the seller it makes no difference: you get a price above scrap value.
The failures I see almost every week
So you know what we're talking about, here are the most common failures on our lot, in plain words: - Snapped timing belt: when it breaks, on most engines the valves hit the pistons and the engine is badly damaged within seconds. A classic when the replacement interval was overrun. - Stretched or jumped timing chain: often announced by a cold-start rattle. On some well-known engine series it's almost built in. - Turbo failure: blue smoke, high oil consumption, no power. The turbo alone is expensive and often brings secondary damage. - Clutch or mechatronics on automatic and DSG gearboxes: jerking, shift shocks, limp mode. The mechatronics unit is one of the priciest parts. - Oil starvation and a seized engine: too little or no oil and the engine seizes. That's usually a major failure. Which one you have already says a lot about the residual value. But even in the worst case the car isn't worthless.
Repair or sell: the honest maths
The honest question is usually: repair or sell? Let's do the maths. A used replacement engine costs roughly 2,500 to 4,000 euros, a reconditioned or new one more like 4,500 to 8,000 euros. Add the labour: removing and refitting easily takes 10 to 20 hours, another 1,200 to 2,800 euros. All in, an engine swap realistically lands at 3,500 to 7,000 euros and up, depending on the model. The rule of thumb is simple: if the repair costs more than the repaired car would be worth, it's an economic total loss — then sell. On a twelve-year-old diesel with 240,000 kilometres, a new engine almost never pays. On a well-kept four-year-old car the maths often looks different. Age, mileage and residual value decide, not gut feeling.
Not every gearbox fault is the same
With gearboxes people cry total loss too quickly. But not every gearbox fault is the same. On an automatic or DSG box it's often only the mechatronics or the clutch, which runs about 1,500 to 4,000 euros depending on the car. Sometimes it's just a sensor or an overdue oil change. A complete replacement gearbox starts around 2,000 euros, while a factory-new automatic can cost up to 10,000 euros. That's why it starts with a diagnosis. And again: even with a badly damaged gearbox the car has value — the body and a healthy engine are real money.
The car won't start — we come and collect it
The most common line on the phone is: but the car doesn't run anymore. No problem. We collect non-running vehicles on a trailer, and pickup is free within range of our sites in Roost and Bertrange. You don't need a valid Contrôle Technique or roadworthiness test to sell to us. The easiest way is to send a few photos in advance and describe what happened, so we can quote a price before we even set off. We usually reply to form enquiries within 24 hours, and payment goes by SEPA transfer, most often on the same working day. Where the car is registered only changes the paperwork, which we handle: in Luxembourg the sale is reported to the SNCA within five working days; in France the déclaration de cession runs through the ANTS portal within 15 days, and if you sell to a registered professional they report the purchase for you; in Germany the car is deregistered with its vehicle documents. The fact that it no longer runs changes none of this.
Watch out for phone buyers, and my advice
A word of caution, because broken cars attract some dubious characters. Be wary of phone buyers who quote a fantasy price sight unseen (4,000 for your BMW with engine damage, we'll be there tomorrow) and then slash it on the spot while you're under pressure — a serious buyer quotes after photos and a diagnosis, not blind over the phone. And in private sales, never fall for advance-payment tricks: a supposed foreign buyer who pays before seeing the car, sends a fake transfer confirmation or asks you to prepay a transport company. No money up front, no contract without a firm price, payment only by traceable transfer. My advice: don't panic-sell below value. The fault is annoying, but the car has a real, often surprisingly solid residual value. Take a few photos, have the fault read out if you can, fill in the form and wait for the offer. It costs nothing and commits you to nothing.
Frequently asked questions
Is it still worth repairing a blown engine?
It depends mainly on age, mileage and residual value. If the repair costs more than the repaired car would be worth, it's an economic total loss and selling makes more sense. A used replacement engine, including fitting, comes to roughly 3,500 to 7,000 euros.
How much is a car with engine damage still worth?
There's no flat answer: make, year, model and type of damage decide. It ranges from a few hundred euros for an old small car to several thousand for a newer or premium vehicle. After a few photos we give you a concrete figure.
Do you collect a car that no longer runs?
Yes. We come with a trailer, and pickup is free within range of our Roost and Bertrange sites. You don't have to push or tow the car yourself.
Do I need a valid technical inspection to sell?
No. To sell the car to us you don't need a valid Contrôle Technique or roadworthiness test. We also buy vehicles that would no longer pass inspection.
How fast do I get paid?
Payment is by SEPA transfer, as a rule on the same working day. We usually reply to your form enquiry within 24 hours.
Engine or gearbox damage? We'll make you an offer.
Send a few photos or describe the fault, reply usually within 24 hours. Free collection of non-runners, payment most often on the same working day.
