well, I visited the dealership in Grand Blanc, Michigan(it is a BMW and MB dealership) where I got My E55 AMG.

They offered me the new E70 4.8 $2500 below the MSRP, and I was shocked when the salesperson said that he is offering me big $$$$ for the trade in, even he said the trade in value is not final since he going to call someone who buys those cars and send them overseas, I will let you know about the final trade in value once confirmed.

I recomend Grand Blanc (BMW, MB, and Toyota)
