Coworker of mine pays $400/month, $2000 drive off for a 350 F with ML for 27 months. Located in SoCal. Not sure how he bagged that deal but he showed me the papers. Go figure.
I'm going to need the MSRP, MF(best is usually .00085 with great credit but if you add MSDs, it goes lower), Negotiated price and area Tax percentage to figure that out. Plus you only said it has ML, so I'm assuming it doesn't have NAV, BSM, trunk rug, etc. Drive off fees are only about $1k. He could have put that $2000 in the car or the drive off fees. I don't know and I don't want to assume, but he could be getting a bad deal or a good deal.
I got the same offer of $400 a month with $1k drive off (SoCal) for a 350F but it wasn't the color I wanted plus it was probably missing some packages that I wanted in it. It was a nebula gray with black interior and not the UW/RR combo I wanted. I refused to take that deal and now I am happy with my UW/RR even though I'm paying $50 more monthly.
Paying $535/mo in Philadelphia (city tax, ouch) for a 350 AWD F-sport w/ Nav & ML. No money down, I did do multiple security deposits. 10k / 36mo. I had it special ordered back in October - came in January.
