I negotiated $2K off MSRP then plus options on my 35d.
But that was in November and the pricing just got released and the vehicle wasn't available for demo. Now that the demo us available, the demand is higher.
I recently talked to some dealerships and they said, if only they had all diesels, they would them all. They been selling all at msrp.

Anyways, just make them an offer and see what the say, if no then walk out to another dealership and see. They may call you back with counter offer.

If any consideration the 3.0i is offering a $4K and 4.8i is offering a $5K cashback if you are not financing through bmw and plus the diff cost between the 3.5d.
So it is around $12K cheaper for the 3.0i than 3.5d.
But yet the 3.5d is still higher demand and out sells both 3.0i or 4.8i.
There are no alternative finance cashback on the 35d due to the demand.
