Used vs. New Car Parts: What's Worth Buying Second-Hand?

Why Consider Used Car Parts?

Used car parts offer serious advantages—especially when sourced from reputable breakers like DRS Car Parts:

  • Cost Savings: Save 30–80% compared to new OEM parts.

  • OEM Quality: Most used parts are original manufacturer components.

  • Sustainability: Reusing parts reduces automotive waste and manufacturing emissions.

  • Availability: OEM parts for older vehicles may be discontinued—used may be the only source.

But not all car parts are created equal. Some are perfectly safe and smart to buy second-hand. Others? Not worth the risk.


✅ Best Car Parts to Buy Used (Safely)

1. Body Panels (doors, bonnets, tailgates, bumpers)

  • These don’t wear out—if they’re rust-free and undamaged, they’re as good as new.

  • Bonus: Colour-matching saves time and money on respraying.

2. Wing Mirrors & Mirror Glass

  • Safe and easy to replace.

  • Check that electric functions and indicators work if applicable.

3. Headlights & Taillights

  • Often just need a lens polish to look like new.

  • Ensure there’s no internal moisture or broken mounts.

4. Alternators & Starter Motors

  • Rebuilt or lightly used units offer huge savings.

  • Look for warranties (DRS offers coverage) or test results.

5. Gearboxes & Transmissions

  • Massive savings compared to new (£1000+ new vs £300–£600 used).

  • Must be inspected for compatibility (use your VIN or gearbox code).

6. Wheels, Steel Rims & Hubcaps

  • Check for cracks or bends.

  • Used alloys can be refurbished to look brand new.


7. Interior Parts (seats, trims, dash panels)

  • These parts don't impact safety and can save you hundreds.

  • Make sure clips and brackets are intact.


❌ Car Parts You Should Always Buy New

These parts wear quickly, are vital for safety, or degrade over time. Avoid buying them used:

Part Why Buy New?
Brake Pads & Discs Safety-critical; wear fast
Timing Belts & Chains Failure can destroy your engine
Airbags & Sensors Can't be retested for safety once used
Spark Plugs Inexpensive; degrade quickly
Filters (Oil, Air, Fuel) Cheap to replace; shouldn't risk contamination

⚠️ Tips for Safely Buying Used Parts

  1. Get a Warranty or Guarantee – All DRS parts are tested and include return options (30 day warranty).

  2. Check Your VIN – Avoid compatibility issues by matching the Vehicle Identification Number.

  3. Ask for Photos or Videos – If buying online, get proof of condition.

  4. Choose a Reputable Seller – Look for auto recyclers certified by the ATF (Authorised Treatment Facility) status.
