VW Tiguan SE 3rd row/ moonroof upgrades

Hey everyone. Need help with this lease deal… Tiguan SE 4 motion, added in 3rd row and moonroof. Also added in maintenance plan for lease period. Sales manager told me that incentives were already built into sale price. Should I try and come down on sales price further? Said it was true sign and drive with first month paid for my VW. Looking at 36/10.
