Volvo XC90 T6 Momentum lease

I have been trading emails with numerous dealers here in Southern California in an attempt to get attractive lease figures for a 2018 Volvo XC90 T6 Momentum. The lowest offer I’ve received so far is the following:

MSRP: $60,490
Discounted price: $55,815 (8% off MSRP before incentives)
$3,000 Volvo allowance (A-plan)
$750 elite bonus
Net selling price: $52,065
39 months/12K miles
Max (10) MSDs
$1,062 drive-offs (first month payment/DMV fees)
$589 per month (tax included)

I haven’t run through the A-plan process yet using my PIN, but the above looks like a fairly standard A-plan deal. Do you guys think a larger discount off MSRP is doable before the incentives are applied? I would love to get something done in the next couple days, but I’m also curious whether the deals could improve if I wait until December.

Thanks in advance!
