When a vehicle reaches the end of its life, most people think it’s worth nothing more than scrap metal. But that’s not true anymore. In 2025, with rising prices for auto components and growing demand for reused parts, your old scrap car might be a goldmine waiting to be discovered.

From engines to mirrors, many car parts can fetch surprising profits, especially when you work with cash for scrap cars companies or professional cash for cars Sydney services. Let’s explore the top 10 auto parts you can sell for big profits this year and how to make the most of them.

1. The Engine

Even if your vehicle won’t start, its engine might still be valuable. Buyers usually look for used engines because new ones are expensive. Mechanics, restorers, and car enthusiasts all search for functioning engines they can rebuild. If your engine still runs or can be repaired, you could earn hundreds or even thousands from it.

Pro tip: Clean it up and provide information like mileage and condition. Buyers love transparency.

2. The Transmission

After the engine, the transmission is one of the most in-demand parts. A working transmission can save other car owners a fortune, making it a hot commodity in the used components market.

Even if it’s damaged, it’s still worth selling to recyclers because of the valuable metals inside.

3. The Battery

Car batteries are no longer just a small part of your car but they have a key source of profit. Hybrid and electric vehicle (EV) batteries can be recycled for cobalt, lithium, and nickel.

Companies that specialise in cash for scrap cars are now offering higher rates for cars with functional batteries.

Eco bonus: Selling your battery for recycling keeps hazardous waste out of landfills.

4. The Catalytic Converter

This small metal cylinder under your car is packed with precious metals like palladium, platinum, and rhodium. Because of their high market value, catalytic converters are among the most profitable parts to sell.

Many cash for cars Sydney services pay premium prices for cars with intact converters, as they can extract and recycle these rare materials.

5, Alloy Wheels and Rims: Style and Strength 

Alloy wheels never go out of style. Whether it’s for aesthetics or performance, buyers love them. Even dented or scratched ones can be refurbished and resold for good money.

Tip: Sell your tyres along with the rims if they are still in usable condition, it can boost your offer.

6. Alternators and Starters

These small parts are the unsung heroes of your car. They’re essential for keeping the engine running smoothly, and when new, they’re not cheap. Mechanics often prefer reconditioned ones because they’re affordable and reliable, making them an easy sell from your scrap car.

7. Airbags and Sensors: Modern Safety Gold

New car models rely heavily on sensors, airbags, and control modules. When these parts are intact, they can be resold to repair shops at good prices. Make sure they haven’t been deployed or damaged, and you could earn a nice sum from safety components alone.

8. Doors, Mirrors, and Windows: Bodywork with Value

Replacing a car door or side mirror costs a lot, so used ones are always in demand. If your scrap car has undamaged panels or windows, body shops or DIY restorers will pay handsomely.

Some cash for cars Sydney services even offer extra cash for cars with good exterior components, since these parts are easy to resell.

9. Infotainment Systems and GPS Units: Tech That Sells

Cars today are as much about technology as they are about driving. Working screens, GPS systems, and speakers can fetch high resale values, especially for premium or newer models.

Pro tip: Include wiring and connectors when selling, buyers prefer complete sets.

10. Scrap Metal: The Final Value
