This works for vans, cars and trucks. With any AI prompt, the better the prompt, the better the response.  The ChatGPT paid version was used to create these examples and non-paid should also work.  

Attached is a high-resolution image of a company vehicle. Create a photorealistic image of this vehicle as a scale model, presented in professional retail packaging aimed collectors of model vehicles. This must look like a real boxed product that would be sold in a specialist model shop. All wording, lettering, logos, and numbers visible on the original vehicle must be carefully observed and recreated exactly. Add the company branding to the outer packaging in a professional retail style. The packaging must include realistic product branding, model naming, and visual design that matches the colour scheme of the vehicle. The vehicle must be shown in a perfectly side-on view, exactly as it would sit inside the carton. No perspective angle, no rotation, and no artistic positioning. Where the vehicle appears dirty, worn, or aged, it must be presented as factory-clean and brand new. The number plate must be blanked out. All other text, markings, and graphics on the vehicle must remain accurate and readable. The model must be shown inside a clear plastic inner sleeve or blister, visibly holding and protecting the toy, with realistic reflections and depth. The carton must appear three-dimensional, with realistic lighting, shadows, materials, and print finish. It must look like a genuine commercial product photograph, not an illustration, drawing, or concept art. No stylisation, no cartoon effect, no artistic filters. The final image must be fully photorealistic and visually indistinguishable from a real product photo. Strictly follow every requirement in this prompt.
