Dealer Blows my 4.8is engine!

[Bnagy4.8]

Update: After a long conversation with the insurance company yet again, the insurance company is going back to the board to see what they can do. At the same time I have involved my insurance company to prevent them from diminishing my cars value. Being that this car is owned my bank they will not allow my vehicle to receive a rebuilt, reconstructed, branded, totaled title.

I got in touch again with my legal advisor/attorney and they said that "if" they put used engine into my vehicle (which they have the right to do) and my value of the car is compromised (which it will) then they are required to pay me for the loss in value based off of a car appraisers opinion. They also suggested that we contact my insurance to get them in the loop on the issue so they can "lean" on the insurance company for BMW.

I will keep this thread updated on any progress.
