Discount on new Cooper - Possible?

[AAAndy]

Just about to help my Dad buy a new Cooper as a runaround(standard, not S). What kind of discounts are people seeing from the Mini dealers at the moment on these.

Would normally expect at least 5-10% when buying a new car but have heard stories of the Mini dealers being a bit tight on this front.

Would be adding on Chilli pack, upgrade wheels to 17in's, interior trim, sun roof, dark glass on rear 3/4.

Managed to get a little more than that, but as suspected there didn't seem to be much room for movement.
