What was your discount off MSRP? Deal looks like there are a few more thousand discount to get down to the deal published by @HN308 (especially since your includes MSDs).
2018 Infiniti QX60 AWD - MSRP $46,310 17% Off 39/10K. $369/Mth - NY/NJ/CT
As @obsessedwithleasing mentioned, Feb 2018 was a record month for qx60, so discounts may be few and far between this month.
