2017 acadia sle 2, slt1

I’m in Nassau county, NY looking for a 2017 acadia awd sle 2 or SLT 1
3 years 36000 or 39 months 39000

Right now I have an offer through the Costco program for 415 a month with just the mv fees and 1st payment down. I’m new to this forum so not sure if that’s enough info to see if it’s a good deal or not. Will the dealers give you the price you are paying, money factor etc over the phone. It seems like they only tell me the monthly cost and I hate going in to dealers, I have been communicating through email and phone with them
