The automobile salesperson is one of many sales professions. The automobile salesman is a retail salesperson, who sells new and/or used cars. Unlike traditional retail sales, car sales are sometimes negotiable. Salesmen are employed by new car dealerships or used car dealerships.
The price of a car, unlike many retail sales, is often negotiable. New cars will often have a factory window sticker listing equipment and options, and the suggested retail price. With the prevalence of the internet, and third party information sites, the profit of dealers has dropped dramatically since prices are widely advertised and best discounts are given to remain competitive. The salesman is paid a commission, rarely a fixed salary but usually based on a percentage of profit, so a deeply discounted price results in a very low commission for the salesman.
The automobile salesman, particularly the used car salesman, has often been a source of characters, often negative, in movies and television shows and cartoons. History and fairy tales often characterize peddlers (people selling goods) as negative influences, or outsiders out to take advantage of people.
