About Buick parts
Buick models share platforms and most mechanical parts with Chevrolet and GMC: the Enclave with the Traverse and Acadia, the Encore with the Trax, the Envision with the Equinox family, and the LaCrosse and Regal with the Impala and Malibu. That makes used OEM Buick engines, transmissions and suspension parts easy to find.
Body panels, grilles, lights and interior trim are Buick-specific. GM part numbers are eight digits, and the RPO code label in the car lists the options that matter when matching seats, wheels and lighting.
