Taking a step back, @aronchi is an experienced broker on this site. His Acura thread is here.
Brokers deals are a good place to start for a price search. For a decent deal you want to get pretty close to the price a broker can publicly advertise on this website.
With Texas taxes, no loyalty (do you already own an Acura?) And needing 10k miles a year you do need to adjust @aronchi prices up a bit. I don’t think the savings would be quite what some of the people above say. However, I do think you could get an MDX advanced trim for 1k a month, which is a significantly nicer car than MDX A-Spec.
You got to decide how much effort you want to put into the search and the value of your time.
