California Sunset Convertible Prompt — Retro Roadside Neon Scene

Create a vertical retro American roadside photograph at sunset dusk. In the foreground, park a glossy red vintage convertible classic car (generic classic American design, no brand badges or logos), its paint catching ultra-detailed reflections of the sunset. Behind it, a glowing red neon sign reading "California" mounted on a street lamp. Add retro American diner buildings, tall palm trees, and a sky full of fiery orange-red sunset clouds. Play up the contrast between the cool blue sky and the warm orange light. Render in a cinematic warm tone with film grain and 8K photorealistic detail. Style: pure California west-coast nostalgia — poster-grade, dramatic, and cinematic.
