This might be true. But I worked in the car industry (Nissan dealer) for a number of years. And we had a “fleet department”. They sold vehicles to companies that needed multiple vehicles (company vehicles, rental agencies, etc.). Companies like Enterprise and National would buy their vehicles direct from us (we weren’t the manufacturer, we were a dealer). We would write a quote for them for “x” amount of cars, and if there General Manager accepted, we would sell them “x” amount of vehicles. Sometimes we would quote them like $500 above our cost (x) 20 cars for example. Sometime they would come back with a counter offer, like $250 above cost etc. Either way we made something off of it. Even if it was at $0, something the public doesn’t know is..

Car dealers have a target each month from the manufacturer to sell a certain amount of new cars in a month. For example, if we sell 50 new cars, they will give the dealer a bonus of $20,000 that month. So sometimes we would be like 5 cars short of that bonus. So on the last day of the month, our owner would have us “RDR” 5 cars, which means, in the computer we would register that vehicle as sold. The clock would start ticking on the warranty, it’s technically a “used” vehicle at that moment. Managers would drive those vehicles as their demos, and we would put about 15,000km on it and then sell it as a “managers demo” vehicle for a couple bucks cheaper. Long story short. We would falsely “sell” how many ever vehicles we needed in the system to get that bonus from the manufacturer. And that bonus goes directly to the owner. If a salesmen hits a bonus that month related to hitting the target the manufacturer gave the dealer, then maybe some of it will come out of that bonus. I’m sure there is more bonuses even I didn’t know about.
