Car Supermarket <kar ˈsuːpəˌmɑːkɪt> Car Supermarket refers to the largest of car dealers or car dealership groups. Typically characterised by offering cars from multiple manufacturers, with a strong focus on choice and savings. Although most car supermarkets will specialise within a specific band of vehicles with regard to age and mileage, the profile of vehicles offered can vary wildly from supermarket to supermarket. While most predominantly stock used vehicles, some specialise in nearly new cars – often offering huge savings and providing a great opportunity to avoid the steepest part of a cars depreciation.
