Careers Sales

Hello, I am interested in the job car salesman and would like to know if there are any differences between used and new car salesman in terms of requirements and earnings. I come from the sale (but furniture industry ), however, was lucky to introduce me to an Audi dealer. There I had been positively welcomed and made the suggestion to hire me as a used car salesman. However, I would rather be new car salesman,au if it is more difficult to get a foothold there, you have the opportunity to build your own customer base. Would be nice to find out ! Greetings Micy
