X3 custom order discounts?

My folks want to custom build/order a BMW X3 to spec. We looked at statewide inventory (CA) with a salesperson at East Bay BMW, came up kinda short. Hadn’t talked numbers yet but they decided to custom order a car since the turnaround wasn’t too far out.

Naturally I want to take the MSRP/build to a few dealers and see what they’ll come up with though curious what to expect in this scenario. I’m more inclined to have them get it from a dealer in Socal that can offer better pricing as they typically do compared to the Bay Area.

Looking to submit order within the next week or so. Appreciate any input/advice here.
