Need help negotiating GLC 350e lease

Hey! I’ve been reading the forums about everyone getting great deals on the GLC 350e, how can I get this lower? https://i.gyazo.com/29222bc80a7e315cfa934d1ebf4497c7.png

Im open to 24 or 36 month lease, 24 seems to give you a better residual. 10k miles

There is the federal rebate of $4460, as well as a $2000 rebate from the factory. The remaining $5000 discount is from the dealer.

What more should I ask for, should discounts be placed in different orders? What can I do to get the monthly price low to mid 300’s

Thanks!
