Original, Aftermarket or Used Parts: What to Ask Your Brentwood Body Shop

Three kinds of parts

When Mashore Autobody or any shop writes an estimate, each part is usually one of three kinds:

  • Original (OEM). Made by or for the car's manufacturer, the same as the part that came on the car.
  • Aftermarket. Made by another company as a replacement. Quality ranges from very good to poor.
  • Used or recycled. A real original part taken from another vehicle.

Why it matters

Fit, finish and how a part behaves in a crash can differ between kinds. A shop and your insurance company may also disagree about which kind a repair should use, because the price differs.

Questions to ask any shop

Ask the shop these before you agree to a repair:

  • Which kind of part is each one on my estimate?
  • Can I ask for original parts, and what would that cost?
  • Will the car be repaired to the maker's procedures?
  • What does the warranty cover?
