Yes, you can absolutely sell a car with engine problems, but your selling options and the final price will be significantly impacted. The best route depends on your primary goal: maximizing profit, achieving a quick sale, or simply getting the car off your hands without further investment. Disclosing the issue upfront is not just ethical; in most states, it's a requirement to avoid future liability. The most common paths are selling to a private buyer who understands the issue, trading it in at a dealership, or selling it for parts/scrap to a junkyard.
Your selling price will be a fraction of the car's value in good running condition. For a common car like a 2015 Honda Civic with a blown engine, here’s a rough comparison of potential outcomes:
| Sale Method | Estimated Offer | Key Consideration |
|---|---|---|
| Private Sale (As-Is) | $1,500 - $4,000 | Requires finding a knowledgeable buyer (e.g., mechanic, DIY enthusiast). |
| Dealership Trade-In | $800 - $2,000 | Convenient; offer is often lower but may be offset by a new car purchase tax credit. |
| Online Car Buyer (e.g., CarMax) | $500 - $1,500 | Quick, no-hassle appraisal, but they heavily discount for major mechanical issues. |
| Junkyard/Scrap Yard | $200 - $600 | Based on the weight of scrap metal; the absolute fastest way to sell. |
Before listing the car, gather any maintenance records. This proves you've taken care of the vehicle, which can make a buyer more confident that the engine problem is an isolated issue. Get a pre-sale inspection from a trusted mechanic to fully diagnose the problem; having a concrete repair estimate allows you to price the car realistically and shows transparency. Be prepared to negotiate aggressively, as buyers will factor in the high cost of an engine repair or replacement, which can easily run from $3,000 to over $8,000. If the repair cost approaches the car's value, selling for parts or scrap is often the most sensible financial decision.

I sold my old SUV with a knocking engine last year. I was straight-up about the problem in the online ad, took a bunch of clear pictures, and mentioned I had all the service records. I got a few lowball offers, but a guy who was a mechanic himself contacted me. He knew exactly what he was getting into, we agreed on a fair price, and he paid cash. It was easier than I thought, just be honest and don't expect top dollar.

Trading it in is the easiest path if you're another car. The dealership will give you a wholesale price, which will be low, but it saves you the hassle of dealing with private buyers. The big advantage is that in many states, you only pay sales tax on the difference between the new car's price and your trade-in value. That tax savings can sometimes make up for the lower offer on your old car.

From a standpoint, failing to disclose a known major defect like engine problems can lead to a lawsuit for misrepresentation. Most states have "as-is" laws, but they don't protect you from intentionally hiding a serious issue. The safest practice is to put the known problem in writing on the bill of sale. This protects you from a buyer who later claims they weren't aware. It's not just about being ethical; it's about avoiding a costly legal dispute down the road.

If the cost to fix the engine is more than the car is worth, consider selling it for parts. List it on Craigslist or Facebook Marketplace as a "mechanic's special" or "parts car." You might be surprised how much you can get for the catalytic converter, wheels, and other undamaged components. Parting it out takes more time and effort, but it can yield more money than a straight scrap yard offer. Otherwise, a junkyard will tow it away and pay you based on its scrap metal weight.
