I have been in the business for years an held a job as Internet director and business development manager.
As everyone has said, money and sales is all dependent on the market you are and the dealership you work at. Pay plans vary widely.
People buy if it is the right car, from the right person at the right dealership. Listen to your customers needs and sell yourself.
It is a great business and great money.
Pm me of you have any other questions.
