Free shipping • 6 month warranty • Lowest Prices


Every part sold from My Auto Store’s inventory comes with our standard 6 month exchange warranty. If your car-part goes bad within 6 months, simply return it to us for a replacement car part. See terms & conditions below.


Before your car part makes it to your door, you can be assured that it has gone through four levels of quality control.

  • Pre-purchase inspection
    We purchase our donor vehicles in-person at insurance auctions. Prior to purchasing, our buyers complete a thorough visual inspection, examining the vehicle’s mileage, the running condition of the engine and the overall condition of the vehicle’s body and interior parts.
  • Inventory
    Once a donor vehicle reaches our facility, one of our specially-trained inventory professionals combs through every nook and cranny of the vehicle, examining and taking note of the specific condition of each drivetrain, body, suspension and interior part.
  • Dismantling
    Before parts are removed from donor vehicles, our team of dismantling technicians are trained to re-inspect each part for fluid leaks, engine compression, accident damage and missing hardware.
  • Pre-delivery inspection and sign-off
    Whether shipped by way of UPS or delivered personally by one of our delivery drivers, no part leaves our facility without a pre-delivery inspection and sign-off from one of our auto parts specialists.
