Leasing a new 2017 vs 2016 or pre certified

HI! I am new to the site. I am looking to lease a new SUV and wanted to find out if i can get a better price leasing a new 2017 either lexus rx350 or infiniti qx60, or a pre-certified lexus, or infiniti? I am looking for a monthly lease of under $400 (if possible). I live in NJ.
thanks!
