Traffic: model pages have to outlive the stock
The searches in this category name a model and a condition, and they keep being typed long after any individual unit has sold. A store built as a page per listing loses its position every time something sells, which means it starts again every month. A store built with a permanent page for each model, showing whatever units are currently available and explaining what the grades mean for that item, accumulates links and rankings over time and hands the visitor to the specific unit underneath. Guides on grading, authentication and what refurbished actually involves sit above both and bring in people who have not yet decided to buy used at all.
