Generate a high-resolution, fully realistic image of a 2025 Honda Civic,in grey, with a sleek and modern exterior, futuristic wheels, and a shimmering body color, displayed in a luxurious showroom with a large logo on the back wall. The image should be highly detailed and realistic, with accurate reflections, shading, and lighting. The car should be positioned at a slight angle, with the front grille and headlights facing slightly towards the viewer. The background should be a clean and minimalist gray or white color, with a subtle gradient effect to give the image depth and dimension."
