So if I'm getting this right.. your '16 +$3500+tax(on the difference) and tags so saying like ~4000 total bottom line figure you have a brand new '17 AWD GT w/premium?
If yes the only question I have is why have you not already done so..btw this seems too good to be true.
My 2016 + $3750 which includes doc fees / registration / VIN etching but not tax which is 7% (in NJ) [Apologies - I double checked with them and you're correct everything but tax and initially they said registration but I got them to take in registration] provided I use Mazda Finance at 0.9% APR [already checked and yes - based on my credit score I'll get that rate].
My current 2016 for which I started paying finance EMI from January 2017 is paid off as of Feb. 2018.
Yes - this is a very good deal since I get some sort of 2017 discount (as I am not buying 2018) + loyalty and some special dealer incentive from re-buying from same place : $400.
BUT - as many stated - dealer also confirmed there might be revision to style / packaging on 2018 mid-year. Initially, my intention was to buy it so that son when he turns 17 can use it, he's currently 10. I never wanted to trade it but this deal looks really good. After driving the loaner 2017 - 1 think even my wife agrees (she cares nada for handling/responsiveness/etc.) that (1) at least 3 times more quiet (2) less roll/pitch/bump/thump.
