Are geo prizm parts the same as a Chevy Prizm?

Yes, the Geo Prizm and Chevrolet Prizm share many parts, as they were produced during a time when General Motors owned the Geo brand and collaborated with Toyota on the vehicle's design. Both models are essentially the same car, differing mainly in branding and some minor cosmetic details. Consequently, most parts are interchangeable between the two, though it's always advisable to verify compatibility for specific components.
