[dennis in se pa]

I am considering getting into the car business as a salesman. What is the accepted compensation for this business? Or is it a mixed bag? Here is some of what I am being presented:
1. I will be able to sell new, used and trucks.
2. Paid training of $500/week + $100 per car sold during the first 90 days.
3. Straight commission after that. (Thought there would be a draw off of the commission)
4. Only 1 week vacation after 1year, 2 after 2 and 3 after 10. I am sure this has to be negotiable if you are good.
5. Health Insurance, although they have not shared the specifics with me on this.
6. This is a Ford Dealership east of Reading PA (Southeast PA).

What do I need to know before I take this jump?
They tell me tthings have slowed some, but cars are still moving.
