Create a detailed 3D model of a 1980s car rearview mirror, emphasizing its classic design. Include a rectangular mirror with slightly rounded edges, encased in a black or gray plastic frame. Add a small, manual day-night adjustment lever at the bottom for glare reduction. Mount the mirror on a simple, functional stem attached to a windshield base. Incorporate subtle signs of wear, such as minor scratches on the glass or scuffs on the plastic, for a realistic vintage look.
