"Design a vintage-inspired T-shirt featuring a classic muscle car. The car should be the focal point, with a detailed and dynamic illustration showcasing its sleek lines and powerful presence. Above the car, include the text 'Pure Muscle Power' in bold, retro-style lettering. Below the car, add the phrase 'American Legend' in a smaller, complementary font. Use a color palette that includes deep reds, classic blacks, and metallic grays to emphasize the car's classic appeal. The background should be a simple, contrasting color to make the design pop." --style raw --s 750
