There are definitely quirks to the way car dealerships are run. I imagine there are similar 'weaknesses' in just about every industry if you put in the due diligence to find them. I always find it somewhat comical when incentives backfire in interesting ways. There are a bazillion tales from HR/Recruitment/Salespeople out there about spectacularly stupid incentives, and I can't help but read every single one of them.

If you end up with a similar situation in your next vehicle purchase it might be worth writing up a blog. I know I'd read it!
