Quality is a term used to signify excellence of a product or service. We think of a quality product, for example a B.M.W. motorcar. We know its well designed, well built and will therefore last a long time. If we think of car of being low quality, we think of something like a base model type of Citroen or Peugeot, with its flimsy panels, cheap components and low specifications.
