What Are the Most Valuable Parts of a Car When Scrapped?

10th Jun, 2025

When your car can no longer be on the road, your first thought might be to scrap it for a single payment. This is a simple and quick option. However, this approach can mean you miss out on the hidden value inside your vehicle. Selling certain valuable scrap car parts separately can often put much more money in your pocket before the car is recycled.

At Scrap Car Network, our goal is to give you the information you need to get the best deal. Important parts like the engine, catalytic converter, and modern tech systems have significant value on their own. By knowing what to look for, you can sell these items to the right people and maximise your earnings. Afterwards, we can handle the safe and legal recycling of what is left.

The Most Valuable Scrap Car Parts You Can Sell for Cash

First, you need to know which parts are in high demand. Mechanics, car enthusiasts, and specialist recyclers are always looking for specific components. These parts are wanted for either their reusable function or the precious materials they contain.

Engine and Transmission: The Mechanical Heart

The engine and transmission are the powerhouse of your car. They are almost always at the top of the list of the most valuable scrap car parts. Even if the car’s body is damaged beyond repair, these core components may still be in good working order or have parts that can be salvaged.

Specialist garages and mechanics buy used engines and transmissions to refurbish them. A refurbished part is an old part that has been professionally cleaned, repaired, and tested to work like new. Because there is a strong market for these, you can get a much better price selling them separately than you would from their scrap metal weight alone. Depending on your car’s make, model, and the condition of the parts, they could be worth hundreds of pounds.

• Estimated resale value: £100–£1,000+
• Best places to sell: Local mechanics, second-hand auto parts dealers, online marketplaces.

Catalytic Converter: Your Car’s Hidden Treasure

Very few car parts are as valuable as the catalytic converter. This device is part of your car’s exhaust system, and its job is to turn harmful pollutants into less dangerous gases. To do this, it uses a thin layer of very expensive precious metals as a catalyst. These metals include platinum, palladium, and rhodium.

The high price of these metals makes the catalytic converter a prime target for thieves and a very profitable item to sell. Before you find out how to scrap your car easily and legally, it is always a good idea to check that yours is still attached to the car. Specialist buyers will pay a high price for them, often much more than a standard scrapyard.

• Estimated resale value: £200–£600+
• Best places to sell: Specialist catalytic converter buyers, Authorised Treatment Facilities.

Alloy Wheels: Style and Substance

If your car has alloy wheels, you are in luck. These are worth more than standard steel wheels because they are made from a lighter and more valuable blend of aluminium. They are also more stylish, so other car owners often buy them second-hand as an upgrade.

Even with a few scratches, a set of alloy wheels can be sold for a good price. Wheel refurbishment businesses can often repair minor damage and resell the wheels. You will always get more for a set of four than if you let them be weighed in with the car.

• Estimated resale value: £50–£200 per set
• Best places to sell: Alloy wheel refurbishers, second-hand parts dealers, local scrapyards.

More High-Value Items Worth Your Time

Beyond the big-ticket items, many smaller parts can add up to a significant amount of cash. Taking the time to remove these can make a real difference to your final payout.

Car Battery

A car battery may look small, but it is packed with valuable lead. The materials inside are highly recyclable, and many scrap dealers and battery centres will pay you for them. If your battery is still fairly new and holds a good charge, you might even be able to sell it as a working part to someone looking for a cheap replacement.

• Estimated resale value: £10–£20
• Best places to sell: Scrap metal recyclers, battery disposal centres.

Starter Motor and Alternator

The starter motor and alternator are key parts of your car’s electrical system. The alternator keeps the battery charged while the engine is running, and the starter motor gets the engine going in the first place. These parts are built to last and often work perfectly fine even when the rest of the car has failed. Mechanics regularly buy these used to save their customers money on repairs.

• Estimated resale value: £15–£100 each
• Best places to sell: Auto part retailers, mechanics, and online part platforms.

Infotainment and GPS Systems

Technology in cars has come a long way. If your vehicle has a built-in infotainment system with a touchscreen, sat-nav, or a premium sound system (like Bose or Harman Kardon), it could be very valuable. Owners of older cars often look for these units on eBay or at car audio shops to modernise their own vehicle.

• Estimated resale value: £100–£500
• Best places to sell: Car audio shops, online marketplaces, and second-hand part dealers.

A Practical Guide to Selling Car Parts

If you decide to sell parts yourself, a structured approach will help you get the best results safely.

Step 1: Research and Identification

First, identify all the valuable parts on your specific make and model. Search online for what parts from your car are most in demand. Check forums and online marketplaces to see what similar parts have sold for recently. This research will help you set a realistic price and not waste time on items with little value.

Step 2: Safe Removal and Necessary Tools

Next, you need to remove the parts safely. This is the most difficult step and requires some mechanical skill. Always consult a repair manual for your vehicle (like a Haynes manual) before you begin. You will need a good set of tools, including socket wrenches, screwdrivers, and possibly a car jack and axle stands to work underneath the vehicle safely. Never work under a car that is only supported by a jack.

Step 3: Cleaning and Photographing Your Parts

Once a part is removed, clean it thoroughly. A clean part looks more valuable and shows that it has been cared for. Take clear, well-lit photos from multiple angles. Make sure to photograph any part numbers or serial numbers, as buyers will often ask for these. Good photos can make a huge difference in how quickly your item sells.

Step 4: Finding the Right Buyer

Finally, it is time to sell. You can list your items on general sites like eBay or Gumtree, or on specialist car part forums. When you write your listing, be honest about the part’s condition and include the part number. For heavier items like an engine, you may want to list them as “collection only” to avoid high shipping costs.

Selling Parts vs. Scrapping the Whole Car: Which is Right for You?

So, should you take the time to sell parts, or is it better to scrap the car in one go? Both options have clear benefits, and the best choice depends on your situation.

The Case for Selling Parts Separately

• Higher Earnings: The biggest advantage is that you will almost always make more money. The sum of the parts is often worth much more than the whole.
• Good for the Environment: Selling parts for reuse is the most environmentally friendly form of recycling. It extends the life of a component and reduces the need to manufacture a new one.
• A Rewarding Project: For those who enjoy working on cars, dismantling a vehicle can be a satisfying and educational project.

The Case for Scrapping the Whole Car

• Convenience and Speed: Scrapping the whole car is fast and easy. You can get a quote in seconds and have the car collected in a day or two, with money in your account quickly.
• No Technical Skills Needed: You do not need any tools or mechanical knowledge. The entire process is handled for you.
• Saves a Lot of Time: Selling parts can take weeks or even months. Scrapping the entire car is a single, simple transaction.

For many people, the ideal solution is a mix of both. You can sell one or two of the most valuable items, like the catalytic converter or alloy wheels, and then let us handle the rest.
