Create a visually striking scene featuring a classic 1970s muscle car with a sleek and powerful design, painted in deep purple and blue hues with metallic reflections. The car speeds down a futuristic highway, leaving a glowing comet-like trail of light behind it. Surround the car with a cosmic sky filled with vibrant colors of purple, pink, and blue, blending into a dreamy galaxy of stars, nebulae, and a prominent crescent moon. Ensure the overall composition combines retro and futuristic elements, evoking a sense of speed, adventure, and otherworldly energy
