Looks like that is a pretty loaded QX60. I have seen people getting under $400/mo sign and drive on 2017’s with an MSRP of around $47k, so it seems like you have more room for negotiation. That is over the 1% rule
There have been QX60 deals posted with $10,000+ off of MSRP. I would keep negotiating or wait as others have said. Infiniti isn’t very transparent about their incentives, but if you check Autobytel there is only $1,000 dealer cash or something like this this month. Pretty terrible.
