, any new car dealer I ever knew had a problem you won't believe. Even though it is all the same company, there are different parts of it. For instance, the sales dept. sells the cars and the service shop repairs whatever needs doing before the car is delivered. But, the service dept. charges the sales dept. for whatever work they do, and they don't get a discount either.
If you trade in an old clunker, the sales dept. puts it on the back lot and when the wholesalers come around looking for stuff they can steal, that old clunker is often lumped into a group of other wholesale pieces, and the wholesaler has to take the junk with the decent ones.
Why is it ok to palm off a dangerous death trap on a dealer when it's not ok to sell it to a private party with a caveat?
