C63 pre-order dealer recommendation

[Jabes]

I'm looking to pre-order the new C63S. Drive the Deal is showing it at about 8% discount, but my local dealer so far does not want to play.
Anyone any ideas on what I could expect to be able to negotiate from a Mercedes dealer? And if anyone has a particular dealer they know is being kind in this regard perhaps a PM if they they don't want to say outright?

Looking forward to going back to an AMG after 3 years in my RS5
