Do you really need to have the car physically in order to sell it? Can't you just have a comparable display model that is used for test-drives? When sale progresses, then you can show them the actual vehicle and sell it to them for a discount.
If the dealership only sells new and last year’s models, it’s probably less of a problem, though there might be a situation, when there’s only one or two models with a specific level of trim (that the potential buyer is interested in) left in stock and they’re all rented out. Assuming that all of these cars have similar levels of wear, which is not always the case. And even then many potential buyers prefer to have a look a exactly the car they’re buying.
And if it’s a used car dealership or a dealership that accepts trade-ins, there’s going to be a handful of models in single quantity.
