I need a clean, modern website whose sole focus is to showcase cars attractively and intuitively. The site will serve as a visual catalogue rather than a sales platform, so high-resolution galleries, smooth image sliders, and well-structured spec sheets are essential. Key things I want to see built in: • A responsive front end that looks great on desktop, tablet, and mobile. • An admin area where I can upload new vehicles, edit details, and reorder images without touching code. • Fast-loading pages, even with many high-quality photos. • Clear sections for technical specs, feature highlights, and an optional video embed for each model. Tech stack is flexible—WordPress with a custom theme, React + Next.js, or another framework you recommend—as long as the final result is easy for me to maintain. Please outline your proposed approach, tools or plugins, and an estimated timeline when you reply.
