Lease Buy Backs by Dealer

Can anyone provide information regarding the amount paid by a franchised dealer at the conclusion of a lease in comparison with the manufacturer’s residual?

One of the ones I was familiar with was BMW lease buyouts but looks like that has changed this summer. The centers now get penalized if they are caught doing what they used to do (buying at cheaper market value price and turning around and selling it to the original lessee).

Thank you.

Awful news to say the least.
