Discounts on '15 and '16 650's

[karter7799]

Been lurking for a while and now starting my search for a new 6.

Any advice on MSRP discounts for a new 2015 650xi vert or 2016?

Looked at a 2015 leftover and was offered about 25k off the sticker (108K) right from the start. Is there more room do you think? Did a vin lookup and based on the build the car has probably been on the lot 20 months or so.

What about discounts on a 2016?

Any advice/sharing of your deal would be greatly appreciated.

Thank you.
