Looking to move up and move on

Currently in car sales, doing well, at the highest grossing dealership in my state. Could move up to a manager or a finance manager in a year and make more than I am, or I could move to other sales.

Looking to make about $200k per year in the next 1-3 years depending on the route I take.

What I'm asking:

  1. Courses that might help me
  2. Alternative fields/jobs

Information: I work maybe 45 hours a week, don't want to go to far over this - obviously I would add course time on top of I'm increasing my skills, but 60+ hour a week sales jobs are not for me at the moment - they used to be but not in love with the idea.

Any suggestions?
