Hi Tony,
Have you heard of Joe Girard? Known as the World's Greatest Car Salesman.
From the site: www.usadreams.com. "In the twelve years he was selling cars from 1966 to 1977 Girard was the winner of the #1 Car Salesman title each year. Joe sold more retail automobiles for twelve consecutive years on a one-to-one basis than anyone else in the world! All his sales were Retail. One car at a time, no wholesale, lease or fleet sales were included."
There are many many great sales people to model. I've been in sales my adult life - so far - and in my opinion, the major similarities with all great sales professionals is Confidence and Determination.
First, ensure you have those areas covered! (if not, read through this site and others .. free resources galore!) If you feel 100% confident in yourself, and 100% Determined to be successful in your choice, then absolutely nothing can stop you. Then make sure you have the basics down.. even old Zig Ziglar stuff (yes - I actually said Zig Ziglar!

) is helpful to get comfortable with the basics. Then.. the sky is the limit!
With money being an issue, perhaps you could go to a library. Perhaps there is a successful salesperson in your dealership that has a library of sales material that he will lend to you. Maybe in your network there is someone else with massive sales success experience, (in any industry) that they would share. Maybe there is a group of people in similar situations to you - starting out - that you could get together with and share.
Thing is, if you are determined to make it happen, you will find a way to do it.
Success to you!
Elaine
