Car leases making profit part 2?

A follow up on my previous question. So dealers sell cars to leasers and thats how dealers make money, because they sell to leaders for the mark up MSRP. The leaser leases it, also charging a mark up with interest, and that is how they make their money? So what if the Ford motoring company was leasing under the name Ford Lease, which is the case. Ford doesn't sell them the cars right, Ford Lease acquires them for no cost, as they are owned by the same umbrella, and therefore can take a car at cost price and go straight to leasing it at MSRP? Is that the case? If so, how can non-affiliated leasers compete?

Thanks again
