Need Help- 2019 BMW 540i RWD

Hi I am looking for good lease for this car and I have sent PM to one of the brokers here 8 days ago and no answer, they must be busy. OK.
One of the BMW dealer in my area has at least 6 of the 2019 540i loaner cars ,with 2.k miles to 4k miles range with msrp of 65,xxx 62,xxx range, online they are offering 5k to 6k discount on msrp because its a loaner. I know thats not really a discount for a loaner, or even on a brand new car , not enough.
With the help from this forum I have no choice but to go for it myself. and try.
what should be my offer to them for 65,xxx loaner. is there any diff approach to negotiate a loaner/demo car then new car?
What would be example of a not a unicorn deal, buy ok/good kind of deal for 65,xxx msrp loaner.
Please help. Thanks.
