Your Regal offers you a lot of driving excitement, so you make sure that you always replace worn parts with OEM Buick parts since they are made to be exact fit replacement parts.

  • Window Regulators – The window regulator keeps the windows moving up and down, and if this part fails, you may be stuck with a window either open or closed. We have regulators, motors and windows.
  • Alternators – The alternator keeps your battery charged, and if it is not working, you may not be able to hold a charge or keep your engine powered. We have alternators, batteries and starters.
  • Bumpers – The bumper is a tough part on your vehicle and designed to absorb the shock of an accident. Should you damage a bumper, you want to replace it and hold your resale value. We have bumpers and other body parts, including safety stickers and labels.

We have an experienced parts staff who can answer any questions that you might have about your Buick Regal. We offer VIN verification to ensure order accuracy, so buy now with confidence.
