Before I got into healthcare, I worked for a company that dealt with the financial statements of dealer networks for the manufacturer. We had several former dealership owners that worked as account managers. They'd give training sessions on what a good financial statement should look like and how to improve. One of the metrics was used car wholesale per unit. The rule of thumb was that if you were making more than $25 per unit, you should have reconditioned and put it out on your used lot. Of course in one session, a dealer had thousands in revenue, with several hundred per unit. That particular dealer was a used car wholesaler and ran the revenue through his dealership. The moral of the story: there's an exception to every rule.
The manufacturer made a profit, the dealer made a profit, the leasing broker made a profit, and the finance company made a profit. How?
