Is there such a thing as car supermarket?

Yes, a car supermarket is a type of car dealership that displays a wide variety of vehicles from different manufacturers in one location. It typically operates on a self-service basis, allowing customers to browse and test drive vehicles at their own convenience, similar to a supermarket where customers can browse and select products. Prices are usually fixed, and customers can take delivery of their chosen vehicle quickly. Car supermarkets often have a large inventory and are designed to offer convenience and variety to car shoppers.
